Not making power any more...

JeffP-Z

I am hoping to get a little help debugging this new issue. So I am not sure if I said this in my previous posts, but I had a little accidental 'money shift' the other week racing. It completely shredded the clutch plate. I have since replaced the clutch with the JWT 1200 lb clutch kit and the 14 lb fly wheel. Also while it was apart, my new Berk resonated test pipes arrived and I installed those. After getting the clutch installed and the car back together this morning, it is no longer making much power. It seems like it wants to idle around 800 rpm now and the almost falls on its face at lower rpm. I had been told by several people that the test pipes should not affect the tune that much (which I was skeptical about) but at this point since I had that money shift, just replaced the clutch, and added test pipes I wanted to ask before just turning wrenches all day. If the release of all that back pressure by changing the cats to test pipes is the cause based on feedback from you guys then cool, but I am concerned that there may have been more damage than just the clutch from that incident. Please let me know your thoughts on this before I just start testing random things like changing back to cats to test, pulling plugs and doing compression tests, etc...

Thanks and Happy 4th everyone!
