With my JWT ECU, I actually have a selectable water injection 'tune' that I use for track days. In my case, the water map isn't setup for more power (as in the tunes are exactly the same timing/fuel wise), but as a precaution and additional safety feature for the hot mid summer track days. It's a night and day difference in regard to performance, as I've forgotten to turn it on at times (mind you I went a few years without it in general) and you can sense the car just getting warm and dare I say not as responsive.

Crank the water map on, and it's like a cool spring day, as the IAT's drop dramatically.

My setup is a bit of a hodge podge...it's a Snow Performance pump/nozzles/anti siphon selenoid, and a JWT ECU with the control for it. I use regular old windshield washer fluid (blue stuff, not the de-icer stuff)


Now with that said, mine is just there for additional safety, and not for additional power. I know some guys have tunes setup with more aggressive timing to make more HP at the same boost level, but (for a reason unknown to me) have always been skeptical of something failing...as in reality it's an overpriced produce sprayer hehe. With that said though, I'm sure I could probably even go up to 24-25 lbs with my gtx2867 (which would essentially be in that 450whp range), but I've never wanted to push it.


(On the SloppyMechanics cars, there were some significant gains through more boost/lower IAT/no detonation running a 50/50 meth mix).
