Slowxr6t Member 516 Member For: 5y 4m 21d Location: New zealand Posted 29/12/19 08:04 AM Share Posted 29/12/19 08:04 AM My 15 fgx has 382rwkw at 15psi with a gt35r and external wastegate. When I accelerate hard its pulling well then it seems to have another big surge. Does the stock ecu on the fgx have the overboost function? Iv heard the sprint does it for like 10 seconds for like when youve gotta do those massive passing manouvers and pass 10 trucks in a row. So could my car be over boosting for a time? Or is it more likely a wastegate issue? Cheers guys Link to comment Share on other sites More sharing options...

Your tuner should have taken it into account when tuning your car. Link to comment Share on other sites More sharing options...

It would be better if it didnt do that I reckon, it kinda doesn't feel right, it should just boost and go not have another surge of power. Link to comment Share on other sites More sharing options...
