Ya, backwwards calculation at 15% loss from flywheel to wheels 547 divided by.85 is about 643 HP at the engine!!......The GM Global warranty language is specific about making changes like this one and about tuning the ECM but I approached my dealer to be safe and after I showed them my shop choice, the hardware choice (same as the GMPP SLP kit) they gave me thumbs up. I have my salemans email saying so.
Be careful with insurance, read my post.
