Tuned a GTO that has been sitting since 2005! It had old pacesetter headers to the H pipe, a K&N cold air intake, and a TSP MS4 cam kit. The trans was completely factory as well as the clutch. Ended up at 28* past peak torque, around 26 at peak torque, and .88 lambda throughout the pull. 93 octane fuel. 425rwhp were the final numbers. Stock 241 heads, stock LS1.
