I think its running really Good for a Sub Zero ground its -11 here today, Roads have salt on them and its still basicly stock other then a Really good Tune and we are still playing with it, I think a 3.5 is deffinetly doable I did run a 3.7 but i cant find the file so the 3.8 will have to stand for now.
Eric you can add this to the performance list!
Big thanks to EPL for helping me tune this Bad boy!
