It is very difficult to spend $3K without being 100% sure you are getting what you paid for. I agree that Dinan should provide dyno graphs proving the accuracy of their claims.

I am also looking at the ESS Direct Flash but their numbers are lower than Dinan. I was told to expect +60rwhp +60lb-ft but they too never produced a dyno graph backing up their claims. At half the price of the Dinan it is quite a bit more reasonable, but I still would like to be sure I am getting the advertised gains.

I inquired with both Shiv (Procede) and Terry (BMS JB4) who are well known in the N54 and N55 tuning community and neither of them took the time to respond to my messages. I also contacted Cobb tunning who is a well respected tuner and their response was that they currently having nothing planned for the N63 in the 50i.

Finally, I have seen some new info released by Active Autowerke but the numbers are the lowest I have seen.

Would anyone with a tune like to meet up with a stock vehicle and do some side by side comparisons? This would be a very easy way to quantify the real world gains...
I am sure it would be appreciated by many of us that are on the fence!
