All I can say is WOW.
The dyno was lower than I expected, but that was without meth. (490 hp 480 torque)
The rough idle was due to a broken wire in the harness extension.
The installer did not install meth injection due to a percieved missing wire. I got home and traced wires and located the right spot in the harness. Install was easy after that since I already had everything else ready.
I took it for a test ride, and it was a blast. The meth injection did make a difference. Every start was a WOT. Pure joy.
PICS later. It is dark now.
