Also appreciate the YouTube video E92William; lucky mine went smoothly like yours without any FatalErrors

I got this done on my Aussie MY09 E82 125i last weekend.
Unlocked some N52 goodness, super stoked with my 130i Coupe

Dynodynamics in kw.
But I've done a conversion to HP and estimated DynoJet result/gains.

My car went from averaging 24 mpg to 20 mpg after the tune. And it is not from driving like a jackass after the tune. I have NGK laser platinum plugs right now. I'm wondering if that is part of the problem, since the 330i is spec'd with laser iridium. I just ordered a set of laser iridium plugs to try out and see if that makes any difference.

Since i put in the NGK ruthenium plugs everything has been perfect, iridiums should be great too. If your coils have over 100k i would replace those.

Thanks for the tip. It has been a few weeks and I forgot to post an update. I put in new NGK 1208 Laser Iridium plugs. My gas mileage went back up from 20mpg average to 23.2 average, which is pretty close to what I had before. So good enough for me.
