From a 335i to a 345i

Pretty easy, just put a reference mark on the gear, and turn it a few clicks tighter or looser depending on what you need to do, probably a few clicks tighter for a turbo setup since its sucking a bunch more air... if it was the stock tightness it would flap wide open at partial throttle. Just be careful not to lose control of the gear!! My dad tried to adjust his with a big screwdriver and lost it, it's taken him a year of tinkering to get it back to approximately correct.

The reason it took your dad forever is probably because one the AFM is tinkered with, it's near impossible to get it set back to stock, since the spring is 'laser-calibrated' or something like that. "Approximate" is the best it gets.

For that reason, I suggest you find a good used AFM (for what, $50?) and tinker with that.

Yeah, you should be able to get pretty close. Todd from TCD said that the AFM adjustment is basically all they do for the non intercooled setup. Have fun!

I'm pretty sure that's basically what I said... It took him forever because there was no reference mark and he lost control of it. Either way, approximate is better than it was from the factory, since the AFM that he's got on his car (L-Jetronic by the way) is from a 3.0si, and he has a 3.5. Don't worry, we got it covered.
