hey guys, so my car was on the dyno this weekend. does not seem to be going very well. car is boosting nicely, overboost to 1.6 bar, settles to 1.1 bar, at abt 3500rpm, she drops boost to 0.9bar then picks up again to 1.1 bar. what could be the problem here ? also what gear do you guys do dyno runs ? 3rd or 4th gear ?
