I am thinking of Stage 2 myself and I'd be curious on anyone's feedback who has already completed it. I realize the stated power increases will be felt but curious if there are any adverse or side effects. I assume mpg will drop but curious what a real-world example is? - of course I can see it dropping just from the change in driving habits due to the need to test the new software
I'm also curious about if it has any effect on the hestitation I feel unders certain circumstances. I am more hestitant to do the Sprint Booster upgrade (which I understand addresses this) than the Dinan software upgrade. My wife's ride is an '03 540iT and the power just seems to be more "sudden" than on the 535xi.
