My sanmmi sat for a while too, I put the kit in and she run good when she wanted to. Never did perform right. I broke down and got a Weber 32/36. And cut in a 2" exhaust (thrush turbo 30 bucks from A zone), 7' tail pipe ($13). vcMan these sammi really screams now. Yoiu better hold on when the secondary kicks in. Next year maybe a RV 2 cam, calmimi header
Good luck on your hightachis
