The APR DTR8868 is a direct turbocharger replacement for the 3.0T EA839 engine found on the 2018+ Audi S4, S5, and SQ5! This upgrade includes matching software for various vehicles and mods, and provides up to 620 HP (571 AWHP) and 622 FT-LBS (572 AWTQ) of torque all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even ethanol all without any fueling upgrades. Additional HPFP software is available for max output on ethanol and increased protection headroom on pump fuel. Lastly, for dedicated race cars the turbocharger is designed with headroom to go even further on your own!
This is a brand new turbo designed and developed by APR from the ground up. It does not require a core, and there's no additional downtime associated with other upgrade styles. The turbo bolts to the factory location and connects to factory or upgraded components.
Since this turbo was designed from the ground up, and doesn't use any of the factory or factory cloned housings or internals, we had complete control over the design. We've upgraded the CHRA to feature German dual ceramic ball-bearings for smooth and reliable operation with better transient response. This also does away with the journal bearing design on the factory turbochargers. Next the compressor cover was upgraded with an appropriate A/R matched to our larger billet aircraft-grade 6061 aluminum 88mm compressor wheel.
The turbine side of the turbocharger also benefits from our ground-up design. The turbine housing is cast with 310 stainless steel that's designed to take the heat an abuse seen on a road course. The turbine A/R is matched to our new nickel-based superalloy K418 68mm turbine wheel. The system will see low exhaust gas temperature, low exhaust back pressure, low turbo discharge temperature, and low shaft speeds because the system has been properly designed from the ground up for the prescribed power levels. Of course, each rotating group is VSR balanced for reliable operation. This all lends well for customers who plan to use this turbo on a dedicated race car as it has the headroom necessary to push the system further on their own.
Each kit includes the complete turbocharger including a calibrated wastegate actuator and diverter valve. All necessary one time use install hardware is included. The kit even includes an adapter for the APR intake system to provide maximum flow through the system, though the system remains compatible with the factory intake.
Our turbo loyalty program includes a free upgrade from any lower APR ECU stage to Stage 3. If you don't have APR software already, it's just the cost of the Stage 1 tune. Furthermore, there's no charge to upgrade from the stock HPFP software to the upgraded HPFP file, and there's no charge to jump between octanes, including ethanol.
APR Stage 3 software was designed with reliability in mind. It's designed to not spike the turbo hard in the lower RPM band or run on the edge of what the factory rods and pistons have been known to handle. Particular attention was paid toward component protections, for exhaust gas temperature (EGT), back pressure safety (EMAP), turbocharger discharge temperatures, and fueling system capabilities. This was done through accurately adjusting the factory modeling during the development phase. As the need for more fuel increases through rising exhaust gas temperature, the system will lower lambda to cool EGT, but will not excessively tax the injection system with excessive on-times. Secondary protections will limit output for safety. By using our HPFP software headroom is increased significantly, but does so without overdriving the pressure to the injection system. The need for limiting power under extreme prolonged use (Tracking the vehicle for example), is greatly reduced. Lastly, with the upgraded HPFP, output on ethanol is dramatically increased whereas on the stock HPFP Ethanol makes similar power to pump fuel.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me.
I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

ABSOLUTELY A MUST for Omegaverse Girls!!!
I ABSOLUTELY LOVE Jillian West and her books!!! I’m so happy I already bought book two and now I have to buy the others for the Assurance Security series!!
Not gonna lie Val kind of annoyed me at the beginning but she grew on me!! Her men are chef’s kisses!!! Holt annoys me some but I can let it slide. I already bought part two so I’m going to be reading that in between work phone calls!!!! DON’T TELL MY BOSS 😂😂😂😂

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat.
It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.
