UNIQUE APPROACH
It's by reprogramming the very basis of the controller itself that we achieve the results we get - just as the manufacturers themselves work.

GREAT PERFORMANCE
By starting from scratch for each calibration, OEM+ achieves a very different level of performance and drivability. It's never just about winding up the peak power.

PEACE OF MIND
We are uniquely positioned to tap into a vast knowledge base and resources network in our development.

MATCHED TO HARDWARE
No other brand can offer you such a comprehensive 'full-car' tuning solution. Our Performance Parts range is the most complete on the market, all matched perfectly to the OEM+ software.

UPGRADES FOR LIFE
Free upgrades on your car for as long as you own it. Start with OEM+ Stage 1, then we will give you Stage 2 and even Stage 3 Performance Software for free!

RETURN TO STOCK
Should you ever want to return your car to standard, the OEM+ system has the facility to return your ECU to 'True Stock', the exact state it was in prior to installation of OEM+ tuning.

RacingLine has been developing high quality performance hardware parts for race and road cars for nearly two decades - firmly establishing ourselves as the hardware brand of choice for Volkswagen Group vehicles. But we aren’t stopping there.

We have been working flat out over the past two years to develop our OEM+ Performance Software. We believe it to be simply the best ECU Software Upgrades and TCU DSG Transmission Software in the market, conceived from a very different approach. By bringing together a full suite of carefully developed software, all matched to work in perfect harmony with our ever-growing range of hardware, we truly believe that RacingLine Performance can offer customers the most complete range of upgrades for their VWG car.

OEM+ TCU Dynamic Software & Tuning is simply an essential upgrade to get the most out of any modified DSG car.

Several years of road and track development have given us the smartest transmission software on the market: by continually feeding the engine ECU’s torque demands through to the gearbox’s controller, the system dynamically calculates and adjusts the DSG’s variable clutch pressures to suit whatever your power output is.

Meaning that just one RacingLine TCU software upgrade will serve your car from standard, through Stage 1, right up to Stage 3 and beyond. So unlike some, there's no need for a new TCU calibration each time you increase your car’s performance.

Our engineers reprogram the gearbox's calibration inside the TCU (Transmission Control Unit). This allows the transmission to maintain higher torque levels through our dynamic clutch pressure strategy, right up to a mighty 19 bar pressure. The result? Shifts are even faster, giving harder acceleration through the gears, whatever level of performance your car has - up to and beyond Stage 3.

Meanwhile, the driving mode strategy itself is optimised to suit higher power levels, giving a more natural gear selection profile. Flick the car over to manual, and at last you'll have true gear control at your fingertips - no auto-upshift*, no kick down until you command it (or drop back to D/S modes).
Not only that, launch control will get you off the line quicker through allowing more boost at launch and increased launch RPM, combined with a less intrusive traction control in launch mode.

* auto-upshift disable not available on certain gearbox codes

Good budget-friendly option
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
The chair arrived 4 days early and was easy to put together by following the instructions carefully. It feels sturdy and comfortable. It does support the lumbar region of the back and the arm rests are adjustable vertically as well as the head rest. I wish the arm rests were able to rotate in and out for added customization and that the back of the chair could be adjusted up and down for more precise support. But for a budget chair, it does a good job.

A solid chair for the budget conscious sitter.
Color: Black, Size: Pack of 1
While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.

Love this chair!
Color: Black, Size: Pack of 1
I had an office chair that cost $300 more than this chair - had it for years, then things started breaking down on it. I read about this chair and, wow! I wish I had known about it sooner. It's more comfortable and it's not a chore to sit for a couple of hours working on designs. Wonderful design - supports my back well and it's very stable, easy to adjust.

Good chair with some quality issues
Color: Black, Size: Pack of 1
I've been using this chair for 12+ hours a day for the last 5 or 6 months and so far it is much better than my last chair I bought at Staples with a few problems. First, overall the chair is still comfortable when set properly, the cushion on the bottom is a little worn out but is still comfortable and I find the backrest comfortable except for the lumbar support which has very little cushioning and feels like a plastic brick being pushed into my back, however I find that I can keep it mostly out of the way most of the time and it isn't noticeable when I carry most of my weight on my upper back area while reclining. The reclining angle is super comfortable and the mesh on the back is not noticeably worn out. I like the headrest which is made of a cushioned mesh, its not better than a pillow but it's very comfortable to be able to rest your head in a chair you are going to sit in for long hours and gives good support. The arm rests don't feel amazing, they have a very stiff plasticky cushion feeling that I'm not much a fan of in terms of pure comfort but they get the job done as I mostly only rest my elbows on them when typing. The arm rest adjustment has a pretty good height range and I keep them at the highest settings and set as close to the chair as possible. While the chair may be comfortable, I have had some quality issues that bring down my opinion of the chair. First, my right arm rest does not go as high as my left arm rest and I have to set the left one down two positions to match the right one Second, the back rest locking for the upright position is broken but I can rarely get it to work as long as I don't put much weight on the back. I would imagine that most people would want to lock the chair upright as opposed to the other positions. Third, the 3 screws holding in the backrest untighten themselves over time, causing the backrest to move to its furthest back position and rock left or right if I lean on either side. When I tighten them again they will usually last about 1-2 weeks before becoming mostly loose again. There is no danger of the screws completely falling out though, just losing their tightness Lastly, I'm not sure how stable or secure the wood panel at the bottom of the seat that everything attaches to is strong enough, I used to have my armrests adjusted out further from the center but when I would lift up on my arms to adjust my seating position I would occasionally hear a sound of the wood stressing under the torque from the armrests. since I moved both armrests as close to the center as I can this has not happened; I would like them a little bit wider but I don't want to risk breaking the chair over it. Also, one of the factory-installed screws in the bottom seat panel fell out and wont stay back in but I haven't noticed any problems other than the risk of stepping on a screw caused by it While this is likely the most comfortable chair I've ever sat in, I have to give it 3 stars for the uncomfortable lumbar support and the quality control issues. If the QC issues were fixed I could easily give this chair a 4 star review
