This is after a turbo upgrade. Not sure what fuel they were using. Stock turbo maxes out around 18psi and arojnd 370hp and i believe that is on alky and half tank e85 and 93.
I want to see how the engine holds up on the extra power. As of right now its at 468hp and 500 torque with the first tune they tried.
