Well I was told my car dynoed higher than MOST with the MODS I had but I was at 480HP 485TQ with 2 inch Kooks Headers, E85, LT2 manifold, lt5 throttle body, ROTOFAB and Magnaflow axle back.
If you isolate just the E85 mod, that makes about 30-35 HP by itself. The LT2 manifold made about 20HP, the exhaust made about 20HP, and the ROTOFAB maybe 15HP. The MORE impressive aspect though is that the torque curve is VERY FLAT which results in a VERY broad power range. STOCK the car (2019 SS A10) dynoed right at 400HP.
A note about tuners. The VERY BEST of them can produce repeatable results in that if they modded 10 cars with the very same MODS, the power gains should be within 5-10HP of each other assuming no underlying issues. The better ones also typically UNDER estimate the anticipated power gains . There are even a few (VERY FEW) that will mod you car and validate the results by taking your car to the track and producing the numbers they committed to. You should ask to see dyno charts of some of the cars that they have modded as a verification of the power gains if you have any concerns about that.
