Was shocked how well twin pass perform but i think your right about the coolin issues, its given me room at the front that i need for a few things so its stayin on for now,i know the grs performs well from your car but the waiting list wasnt acceptable tbh, anyways be a good comparison to she what it will take in the future as i have an ecu swap looming soon as well as other stuff lol and still on the old engine for now lol
Think Mike G has 1 on his fezzy that was run up at scc and made good power but i may be wrong.
