@black93z28camaro I agree. But believe me, the tune was really bad. They beat the car on the dyno for many hours. I went back to the superchips handheld tune and it beats the haddad tune all day long. Better MPG, better throttle response, just way better all the way around.

Should have just got a timing controller so you could just retard timing when you wanted to spray and put it back for normal. 100 shot would have gotten you way better gains also.
