That makes sense. I didn't know you were so low at 8.5:1. What is your goal for your car? It looks like you could really crank this car up if you wanted to.It's the low compression I need more boost from the turbo to get higher in the hp range naturally aspirated the car only had 310 to the wheels mostly because it was a 8.5:1 motor. I have since picked up 130~ hp on 7lbs of boost kris think if I swap out the spring to a 12lb Spring I'll be around 510
