With the L99 engine a lot of shops try to sell you VVT delete kits mostly because of a lack ok knowledge on how VVT works & how to tune it. We developed our VVT camshafts using a superflow engine dyno which allows us to make a matching VVT timing table for each rpm point up the entire rpm band. The result is a camshaft that uses different amounts of advance at different rpm points.
There's no reason to remove VVT & give up power. If you'd like to discuss the cam packages & how VVT works give us a call. You simply can't make close to the same average power with a non-VVT camshaft as you can a VVT cam.
A perfect example of how well VVT can work is the VVT-3 camshaft makes 100 flywheel HP gain & still brings power in early thanks to the VVT. Most large camshafts give up some low rpm power because they can't be advanced a lot early in the rpm band. The VVT allows you to do just that & the result is you can bring power in earlier!!
