Back on LS1Tech with a new ride
I can run my LS6 M6 Z28 with 4:11's, with the stock LS1 tune through an entire tank on the freeway and get right at 29mpg. It is now tuned and I average about 19-22mpg, per tank with everyday driving( I have a heavy foot to). I had 3:73's for a while and the mileage was pretty much the same. You shift a lot at first with the 4:10, like into second before you are across an intersection but it isnt bad at all,it also makes 5th gear feel more like a 1-1 gear instead of an over drive gear. And yeah, you can blow the tires off any time, any place!

also, going up a wheel size and or tire size would help. Im running 18's with 40 series tires. Do you know what springs you have? They also make 1/2 inch spacers you can put between your strut and A-Arm, it will raise your car 1/2 inch and that might make all the difference.
