I have a boomba wastegate that came on my srt-4 i recently purchases. Read the manual for installing to learn about the boost adjustment. Before, it would spike to 20, then hold 13-14 to redline. So I adjusted the screw clockwise 1 turn (2 psi according to the install) and just got back from a test drive. Car is definately faster (by the seat of the pants and the increasing loss of traction in 2nd
) but now I am getting some pinging that was never there before. At one point, the engine just completely backed off of itself like it smacked the rev limiter (only about 4-5k rpm), let off then it resumed accelerating. I thought with the stock ecu pulled timing when the boost increased, so I am a little confused. I did adjust the boost controller to exactly back where it was before, until I learn more about whats going on. All 3 solenoids on this thing have been de-hosed, so it has no computer boost control what so ever. Was I just pushing it too hard?? CEL has always been on (code for power steering pressure switch and a map correlation code.) Car also has a greddy e-manage but unsure what part its playing right now (no support software or cable, adjustment screws on it seem centered) Can somebody help me, not a complete turbo newby, but definately a srt-4 newb!!
