Higher Octane is critical to achieving the maximum safety, consistency, and power from your supercharged ISF. Our Stage 1 tune achieved a 40hp increase, which translates to about 570whp on our DynoJet, or about 670hp at the crank (see Dyno chart in the photo catalog for this product).

With the new C38R, we found out that the best combination is with addition of water-methanol kit. Therefore, Stage 1 includes water-meth, upgraded pulley and belt and Stage 1 tune.
