You're probably right cookn, I'm only running the common engine mods...ADA head, 38 carbs, carbon reeds, ported cases and exhaust. Nothing special. When I had my dry pipe on, it always had a slight flat spot on the holeshot, the only other enhancer I had seemed to fill in that flat spot. Plus the top end was better in terms of the higher rev limit. But for overall performance gain, I didn't really notice much. The ski sounded cool though when you crack it and the pump hooked up. Made me think of how race skis sound when they go ripping by the finish line. Other than that, I think I will be much happier with OCD's mod work.
Agreed to that jetx, I was fully anticipating being stuck with it or at the very most getting a replacement unit. I didn't hassle them either, just gave them plenty of time and one update about not hearing from MSD. They didn't wait too long to get a refund arrangement started. Because of that though, I rank them highly for their support. I bought it from TDotperformance.com
