Hey guys ive tuned a few of the FG XR6t models now. A few of them have been auto models but recently I did one (auto model) that seemed to be limiting the power output. I hadn't come across this before. The car was in very good condition overall with low km's. Just wondering what might have been causing this? It was making the same power on 15-16psi as it was on 13psi (380hp). Beyond 13psi it seemed to hit a wall, the boost would be increased with no power gain.
It had upgraded valve springs, turbosmart actuator, turbo back exhaust, turbo side intake, upgraded front mount intercooler, upgraded injectors and fuel pump..
Any help would be greatly appreciated. None of the torque limiting parameters I changed seemed to make any difference.
