Hi everyone, I just recently installed a banks wastegate actuator and I am seeing some interesting behavior. The first time I floored it, after install, my boost jumped up to 25psi for a few moments and then I felt the truck suddenly loose power and the boost fell back to ~17 psi. From there on it seemed to maintain that level of power for the rest of the climb. I pulled over and noticed some soot around the exhaust housing on my turbo. So I wrote the problem off as causing a new turbo exhaust leak from the increased drive pressure.
This happened in the process of a series of upgrades I was performing over christmas break. I have since installed stage I injectors and an adrenaline injector pump. What is weird is that it can now easily maintain 25psi of boost but it still has that power loss after a few seconds. With the new hpop I am maintaining a constant 3200psi at WOT, so I am not feeling the loss due to injector pressure that I used to.
Granted I still need to fix the new turbo exhaust leak and the up-pipe leak I discovered in this process, but could the ecu be cutting fuel due to the higher boost pressures? The SES light is not coming on. Any other thoughts?
