Ever get it retuned?

esfourteen

i have an appointment next saturday actually. I did dyno after installing the new actuators but boost was still falling off 3-4 psi up top, the actuators were set to ~11psi, the 2 runs are 14psi falling to 12, and 17psi falling to 13

This was an older dyno jet, which I happened to break after about 15pulls, and for some reason the turbos spooled incredibly slow on this thing. Adjusting gain on my boost controller had NO affect what so ever which tells you it wasnt even getting a chance to adjust anything because load wasnt high enough, where as on the street I can get 14psi by 3200rpm without overshooting target boost.



After this dyno I added as much preload as possible so the actuators are set to 13psi currently, 17psi hold to about 15 now and doesnt seem to drop off as early, but its so hard to tell on the street.

f*ck internal wastegates on this car.
