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.

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!

Great stuff!
Color: #3 Rose Gold
Trying to give 4.5 stars. It’s phenomenal! My only .5 is that is absolutely does rub off on clothing. I’m going to a party tomorrow and I’ll try using setting spray after application. I love it though. Light weight, no odor and shimmer you can use on body, hair and even accessories!

Beautiful, Subtle, Long Lasting Sparkle
Color: #3 Rose Gold
Sprays easily and seems long lasting, (stayed on for more than 3 hours of light household work). The glitter is very fine, and that’s exactly what I wanted, it is not visible dots or shapes- my arms just sparkled when I moved them and with the changing light. Feels like nothing is there. Nice! Doesn’t feel especially moisturizing, but hasn’t dried my skin out either.

Great to have this on hand
Color: #3 Rose Gold
I bought the rose gold to add some shimmer to my body and hair. It's the right amount of shimmer to stand out. Looks super cute, it sticks easily and when you wash it off, the glitter comes off easily. The smell isn't the best, but it isn't terrible. I just use my own fragrance after I put this on. I love the glow it gives my skin and the shimmer it gives my hair. I'm going to buy this product again. Second time buying this and I love it!

4 out of 5
Color: #3 Rose Gold
I loved the glitter. It doesn't leave me feeling gross and sticky. The color is very pretty. The little pieces of glitter are really fine which goes well on clothes and the whole nine. The only thing is, the spray bottle is sad. I had to switch it into a different bottle to actually apply. Overall, I really liked it. I feel like I got what I paid for.
