I'm averaging 29.3 mpg with my city/hwy. Loving it!

 

You just defined the future direction of American performance engines as they move away from V8s and into small displacement V6s and fours that employ SCs and turbos.

 

Just ordered mine this week. The dealer is not a true GMPP dealer but they said it's on it's way. They did tell me July 6th, but then asked for my VIN to put it on critical B/O. Well that's what Honda calls it when something is B/O'd.
Just can't wait now. I see 15psi sometimes but when it does 2-3 shift(auto) drops right to 9psi Hope this STG1 cures this!!!

 

I just put the kit on my auto and trust me, it will...and then some!

 

I went on a 340 mi day trip today consisting of a route through a combination of a state hwy route (55 & 65 mph speed limits) and very rural county/town mountainous routes (45 & 55 mph speed limits) through mid/central NY State.

I had my daughter and wife with me, my daughter's BMX race bike, gear, cooler, folding chairs, end table, etc, the typical stuff you would load for a day's sporting event (my daughter races bikes).

Spirited but safe driving (typically 70mph on state and 60mph on rural routes), I yielded 30.1 mpg with the St1 kit pulling what I consider moderate weight load. I'm impressed to say the least and can't wait until I take an extended run from NY to Fla this summer on an interstate (I95). I'm expecting to see even better mileage.

The car has relentless power now, great throttle feel and did not miss a beat throughout the trip. It ran extremely strong, but surprisingly smooth. It seems to run better overall than before the upgrade for some reason, even when driving it prudently.

It's phenomenal that I never considered this benefit as part of the upgrade. Now that I know what I know, I must say that anyone who has an LNF should strongly consider it for additional reasons other than fun. There's actually a practical side to it which makes it easier to sell it to the wife (and yourself if you're not sure if you should spend the money).

 

Mostly Direct Injected Turbo 4-6 cylinder engines.

With the goverment regs coming few V8's will be left and they will be expensive.
