When I did my dyno run on SAE Smoothing 3 my car indicated a higher result. Then I went back to SAE Smoothing 5 with a lower reading/result. I believe most of us use the Smoothing 5. However, the total results are about right.......76 rwhp increase. Exactly what Jason said it would be between the two cams.......5 to 10 rwhp difference.

According to Jason's graph.....76rwhp gain from baseline. My car made 70 rwhp with the VVT-1 accompanied by the ATI underdrive pulley. Baseline was the typical bolt ons for my car.

Is it a Choppy cam or is fairly tame? Looking for stealth.

I would say fairly tame but not stealth at all. Everybody can notice the cam. I believe a stealth cam would be in the direction of something like the LS9 ZR1 cam. Actually, it a little choppy when you first start the car then moments later is calms down.
