Yep. Now we just need to figure out how to fix that...

Guys I am doing my figures from pumping gas (I filled up 19 gal yesterday and drove 300+miles so far and I still havent reached 1/2 tank) and I am using info from the trip computer. both are correlating really closely maybe off by 1-2 mpg... still it does not negate the fact that at an increased hp level the car is under less strain to hold a given rpm...
for example: maintaining 75mph in 6th gear stock required about 30+% throttle position... maintaining 75mph in 6th gear TT'd required about 22% throttle position... I am seeing an increase in motor efficiency and can sustain higher rpm's with less throttle input. Therefore, the motor is able to get higher fuel economy. mike btw rcz... I have been driving a TT G37 for 2 months now

btw at 75mph i am just under 3k rpm and barely touching the gas maybe 6% throttle... The mileage to empty jumps around on me so I am not using that as my basis... After 200miles yesterday it went from 395 to empty up to 495 back to 450 and so on depending on my driving. Also I believe the trip computer is taking calculations at 1 mile increments and comparing the avg fuel consumption to give you the est. range. If i lay into it for a quarter mile the range doesnt change until a mile or two later and if I am coasting it doesnt change either.
Mike

Hey everyone said me and Semtex were applying ricer math when we quoted his exhaust, HFC combo on hp.... guess what we were right! My math is on target... I have been getting 500+ miles on a tank of gas when i drive it normal...
500/19=26mpg 550/19=28.9mpg 600/19=31.5mpg so with my avg's being around 26-31 combined I should be right on target.

I have the same car/combination (essentially). I have to side with Bullitt, although I understand and won't completely trust the onboard computer (which reads around 29-27 mpg on cruise.) It just sips fuel when I'm not stepping into it.
That said, probably because of exhaust flow (no cats, straight out), the car is effortless at 70mph. The new math: Having my cake and eating it, too. Coop

Turbocharged engines are generally considered to be more efficient than an NA motor of similar or slightly lesser HP level, but I've never heard of adding a turbo system to a car making it more efficient, although if the compression ratio is reduced then I guess it is theoretically possible.

It's not like GTM needed more advertising to sell their S/C and TT systems.. hahahaha..
- Do you have a Z or a G? - Are you having sucky gas mileage? - The answer to your problem is Twin-Turbo! IT WILL PAY FOR ITSELF WITH SAVINGS!
