Your numbers are high for 20%!! Let alone 30.
I don’t need to ask, I couldn’t care less what flywheel hp is. Never have, never will.
I have tuned my own car/s on a dyno. Via BigStuff3. Livernois tuned my raptor. Made 525 on 89 octane. Again flywheel HP is completely useless to me, selling “700 kits” is a marketing ploy and completely misleading. Haven’t seen a engine dyno race break out.... ever. Wheel hp is something that can be looked at. And that still not all that, till it can be put to the ground.
