This Is a fairly new build and I'm having trouble in the higher Rpm range on the dyno. The engine is a built 03 cobra motor with stock heads and cams. posi ported trilogy 4lb lower 3.0 upper I'm having trouble where the car makes good power and then flat lines at 5500 rpm, Fuel is good twin gt pumps 40 amp kb boost a pump, modded fpdm 60lb injector and so are the spark plugs tr6 gaped at .27 and new weapon x coils with a sct 2600 maf. So I have come to the conclusion that I might have a floating valve. and there also a slight head tick on the driver side that I have been noticing. any inputs to what is going on with this car. at first I though there was belt slip but that's not the case
