need "different" kind of performance upgrade input.
So i put on 150-200 miles a day on my e46 325. @$4.00 a gallon, that's some serious $$$$$. I get about 25 mpg (was 27 and dropped 2 when I put the 19's on....ouch, but worth it for the look)
Have seen that remapping can help mpg(as long as you stay off the throttle) what about exhaust and Cai?....anyone have experience????? Other ideas???? Even small gains are worth $$$ @ 40k mikes a year......even 1 mpg increase can result in 60 gallons a year savings. Thanks
