Hello guys, I have Corsa D SRI after remap, downpipe, second cat off, and 2.5" catback. The car had 3 months ago 190HP. In april, my turbo is broken. After regeneration I felt the car was weaker. I went to tuning, and car have 178HP.
I put on larger injectors 395cc and I decided to do a remap. And there is problem. Corsa did 190 HP and can't do more. Turbo can't boost more than 14.5psi. Inlet is okay, MAF is good. Tuner tell me the actuator is okay. 4 years ago in my car was installed ECU from other car, because my is broken. What could be the reason the low boost? Currently tuner fights with it.
