Did you reuse your original clutch pack?I have had mine installed on my shop car for over a week now. It is the best $500 modification I have ever done. No misfires and I have been beating on it hard 19-20psi with stock turbos. The trans feels and shifts like an m4. My flywheel was completely toast all the fluid leaked out and it was only a matter of time until it would have failed catastrophically.
