So I've been testing the New AA tune for the E9x 335i n 135i. I must say the older tune had some issues. One in which limp mode due to breaking 250 degrees on Temp.
Last night at PBiR with the updated Version 2 Tune on 6 runs back to back (due to only 14 cars there) the car did not break over 231 degrees plus an hour n 1/2 to drive to PBiR from miami.
My friend with a current N54 with JB4 tune on his car. Drove my car to test the car's tune. His words was "it's so smooth going up on the RPMs" he was shock because we have almost the same miles on our car over 58k. He said "it feels like a new car".
Power wise WHP and WTQ has improved Dramatically. And since each car is different I can not quote a WHP n WTQ for you. Just get the new tune and dyno it before and after. I can say this NO MORE LIMP MODE, NO more overheating, and More importantly greater GAIN in smoother RPM power bands!
Call Ivan at Active AutoWerke for more details. (305) 233-9300 ext: 234
