Now, once you add the supercharger to the mix, the supercharger is literally shoving more air into the engine, and it has to go somewhere. This extra flow, is what truly allows the Ace to shine.

Even with stock cam timing profiles, if you tune on an Ace header + C38/C30 HBP + pump gas, if you swap on another header with just that ignition timing table, you'll knock before you can redline; the Ace just flows that much more and allows for more cam timing.

Here's an example.




JRSC C30 + Ace header + flex (E70)+ HBP

Thanks for the data, I wish I could have installed the Ace header. With a cat requirement for emissions in NY, it is not happening, unfortunately.
