On a 250-350whp car, we might stick with a stock ECU/piggyback, in which case, reasonable plug gap is possible without a failed spark event, but, above that, I push for my customers to go standalone. With the TEC3, I've run as much as .036-.037" plug gap, on a cold plug, at the 600-700whp level.

Sounds like a good buy for 50 bucks though..

D*ymn, I'd like to see your shop. You're right, of course. When you're building monsters, you don't want weak-sauce sparks. For us normal folk dealing with stock ECUs/coils and needing more sparks, the $50 special works pretty well.

GM coil paks. There's 50-70 Kilovolts at the gap, I bet. Thanks for the view into what your shop creates.
