hello guys sorry I'm kinda new to all this. So when I flash both the rsa delete and 325i_330i tune they both say complete and everything seems ok, but when I go to turn the car on I disconnect one of the disa valves and service engine doesn't come on, wouldn't the service engine turn on indicating disa valve not plugged in. Also the car does not feel like it has gained any significant horsepower. not sure if it's me or the tune is not installing on the car properly.

DISA valves don't cause a check engine light, but they will cause a code.

are you sure your DISA valves work?

Hey Hassmachine thanks for the reply. Disa valves do work and where tested prior to putting stage 3 in, after flash. When disconnecting disa valve no codes thrown, would this indicate car didn't flash properly.

No. If it didn't flash it wouldn't run at all.
