Good point, it also could just be due to the lower compression. I'm still excited because this tune seems to need the 3 stage intake in order to get peak gains and the N51 should already have it. Regardless it would be a great bonus to those who have an N51 128i if we could spend $900 and gain 30 hp. If that's the case I will be forever grateful that I purchased mine while living in Rhode Island.

Evolve should send me a unit for research and development - I'll foot the bill for the dyno runs and send you guys charts and data. My N51 is still stock and only has 46,000 miles on it!!!
