When I had a mild cam and a Maggie my gas mileage was just as good as stock. My car always got decent gas mileage it seems compared to a lot of guys that post.

16.1 mpg right now

Ls3 conversion, Cam, heads, ptb, pim, 1 7/8 SP headers, cai intake, lingenfelter exhaust with x pipe, 25% UDP, 3200 stall, and custom tune

When I had the stock converter it drove fine. But I wouldn't expect stock drivability.

The tune has a lot to do with how the car will drive

Depends on the cam....some might actually work better with a bit higher stall.

I would figure you are going to loose 2-3 mpg in town, and if the car is tuned right....might even pick up 1 mpg on the highway.

That's gotta be your foot's fault?

OP....my car got 11-12mpg in town and 20-22 on the highway with the stock converter. With the 3600 I probably get 10 in town but still get the same 20-22 on the highway depending on how fast I'm going.
Granted....my in town is 2 miles to work stop and go, back home for lunch, back to work, run a few errands, and back home.
