They think it has to do with Ethanol in our gas, its why 98% of fuel pumps fail in the US and 2% in Canada. California probably has it worst. People can point their finger at bad gas, but at the end of the day there's no one to blame but BMW for making a flawed product.

Also i sold my Jb3. Im riding stock. Less hassle imo.

So you want to compare your "Full Road Race Car" ISF to a stock or Dinan flashed 335i? Of course you'll walk away....but if the ISF was stock...you wouldn't. Modded 3 ers are no joke...granted you'd better be running race gas on a high boost map just to stay along side the ISF on the straights.

BMW really has the driving dynamics down, something Lexus is playing catch up with. Even the performance oriented ISF feels somewhat numb compared to the lowly 335i. Of course, I've been to the BMW dealer more times in the last year that the last 8 years of my Lexus.
