Re: gas mileage????
Some do some don`t. It depends mostly on how you drive. Of course it also depends on what mods you have but I am talking basically stock I get about 15+ city with the air running and not sure about hwy until my road trip next month.

Re: gas mileage????
Ya i thought that sounded prett bad too. I saw a window sticker on a 92 with the TBI setup also and it read 17-26. I want to go with the TPI setup on my 305 cause I figured it would be better on gas, but also has a lil more kick.
I have eveything I need, my brother gave me a '88 IROC so I could get all I needed. But will I gain much,? if anything????
