What kind of MPG are y'all getting with a Whipple HO with the FRPP Tune and stock gears?
Thanks

I'm getting 22-23mpg with 3.55 gears, 11 psi of boost, and Adam@ST's custom tune. Not sure what the stock frpp tune gets.
I noticed a 2mpg drop in town, and a 2-3mpg drop on the freeway with 4.10s. (freeway = 75+) this is with a custom tune though, sorry I didn't read the entire post.
I'm not conserned with MPG though, I didn't buy the car to be economical :-D
I would not expect much MPG loss since you really should be out of boost with stock gears. So that it should be running as if N/A until you start climbing on the RPMs. I'm pretty sure Whipples/KB's/Saleens have a bypass for just this reason. It more efficient to have the air bypass the blower since you don't need boost to cruise and it also lower AIT's.
