Thread: ZZP vs cam setup...Gains?

Thanks. Just one more thing I was wondering while we are on the VS cam topic. When installing the cam, do I need to have a custom tune before running the car/driving it or can the car be driven after the install with no tuning? The reason I ask is, I would probably go to Will/Overkill for tuning, assuming I could get a hold of him, but he's a couple hours from me atleast. I can't do it any time soon this year unfortunately, but it's good to research.

I ran the car with no tune, 3.3 pulley and 90# springs for about 4 days and it was really impressive. It sounded great and performed like I wouldn't imagine. But after I took it back to clear a couple codes and tune it, ALL HELL BROKE LOOSE. I was more than happy with no tune, but tuning it helps you stay in the cam's powerband. There is a HUGE difference. I got my shift points set at 6200 and my AFR tightened up, and we wont even talk about the skip shifts... Holy..

Here is a vid of my first day with it with no tune. The tourque is rediculous
