Just not that big on the hype...

Agreed. It would be nice to have a stock F10 n55 with straight before and after. It is tricky to fully judge the tune based on this type of testing because the ECU and the tune need some time together to really achieve peak performance (vs pop in tune and dyno).

Another dude from UAE:

same stuff, different forum:

I agree, that I would love to see before and after dyno numbers going from Stage 1 to Stage 2. Regardless, this mod is going to be the most power for the dolla.
