I posted all my fuel economy data on fuelly since I've had the car. The ti became more and more track oriented over the years but in general on road trips I was still seeing around 30mpg. That's with sticky 245 tires and a 3.73 diff. As with any tune, the extra power initially makes you want to floor it everywhere. Once you're used to it it's easy to drive "like normal" and get good mileage. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
