Overview:

Take control of your GM Gen V LT1, L83, or L86 engine with Terminator X! Do not settle for a factory ECU with a cumbersome tuning interface when you can have complete control of your engine, self-learning fuel strategies and the proven, race-winning technology of Holley EFI at a budget-friendly price!

The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more.

The 3.5" touch screen LCD handheld contains an easy to use calibration wizard as well as tuning and gauge display functions. All Gen V LT Terminator X kits will come with an external Gasoline Direct Injection Controller, which enables the end user to control and tune, factory injectors, GM Gen V LT Variable Valve Timing (VVT), and factory fuel pumps.

Whether you are building, an LT swapped budget beater or a boosted racecar, Terminator X has the features and technology you need at a price that will not break the bank!

Game changer
Color: Black
This kitchen sink organizer has been a game changer for my countertop! It’s sturdy, well-made, and fits perfectly next to my sink. The multiple compartments are ideal for keeping sponges, scrub brushes, dish soap, and even scrub pads neatly organized and within reach. I was able to clear up so much clutter around my sink area it looks so much cleaner and more functional now. I love the rust-proof design and the drainage holes on the bottom that keep everything dry instead of sitting in water.

Perfect Size and Highly Practical
Color: Black
This sink organizer with sponge and brush holder is the size I was looking for. The non-slip, drain-free base keeps everything dry and in place. Having my sponges and brushes within easy reach makes the sink area much more organized, and it fits perfectly without taking up too much space I like the quality. It has genuinely made my kitchen feel tidier and more efficient.

Very good quality
Color: Black
It is easy to assemble and works great with my soap, sponge and scrub brush. And it stands stable on the counter beside the faucet. I think the materials used are of good quality and should last a long time.

Works Good!
Color: Grey
I was concerned it was going to be too small, especially since the tall portion design doesn't allow you to hang on the ourside....But I have a very nice glass container of dish detergent in it, a bottle of hand soap, and the tall container for taller brushes, straw cleaners, etc. It fits everything pretty well. Wouldn't be able to add a sponge to it, but I have a holder with suction cups on the inside of my sink for the sponge and keeps it out of sight, so it works for me. But if you have a stuff at your sink, it probably wouldn't. Though if you like the design (which is very nice), you could always use two, one on each side of the faucet. I also returned one because even though the extra container could hang on the outside, it was short enough and everything kept falling out of it. This taller one works much better...but again, it too is somewhat limited on size and storage. I much prefer everything organized and in its place, and this provides that.
