I run it on my 99 TC, punched to 95ci, cams and head work.
It let my engine over rev when I missed a gear and it caused the spring retainer to break in half. The results was a bent valve, chunks taken out of both heads and pistons. $900 in repairs and all is good again.
I now make my own ignition curve and have all spark cut out around 6200 rpms. I do like that I can advance the rear cyl 1* and make my own curve. For the price, I'm good with it. I even put a TH ECU w/ wide band O2 sensors in my brother's 08 Electra 103 build.

I am happy with the quality of the parts and the ease of installation. The only problem I have is that the software directions I received were not up to date. The tech support was very helpful.
