Yeah my trims are 0'ed out, they cannot get any more perfect. My WOT AFR error % is -1/+1. So i know WOT is dialed in. I have been working on the timing also per the graph. Building it up and dipping it at peak torque and modeling the AFR curve after that. There is not much more work the engine needs, i think the trans tables need a bit of tweaking but thats it. But the trans is fully built like Allen stated so that could be soaking up some HP, but I wouldnt think almost 50! I will see if everything looks ok Wednesday when I install my TR 7.425" pushrods to make up for the base circle on the Z06 cam.
