It feels great! i can definitely feel the extra power, and from what i have read its only going to get better over the next few 100 miles as the tune adapts to my car  from my readings and the modifications i have done i should be getting at least 50+ more hp at the crank and you can definitely tell there is more there then before, quite a bit more, i cant wait to put my summer tires back on so i can really grip the road and see what the car can do now. |
Welcome to the club
. Its good to be here
From my experience & research the (3stage + North American company tune) vs. (3stage only) is alot of new torque in low-mid end and not alot of HP at the top, I think its at or just above a stock 330i.
Dont let it discourage you, I may be wrong as I haven't seen every pre & post dyno ( especially rwd only 328i).
I do know that DISA makes the car breathe and drive much better, like a refinement.
The only companies that claim massive gains are German, and they are elusive & expensive.
