How do you know you have spark blowout? Assuming the stock ignition system is functioning as designed, 18 psi will not result in blow out. I run 24 psi with a .032 gap and have no blow out. I think you have other problems.

I run 25 PSI on my modified engine and 18 PSI on my stock coupe with the factory gap of .034. Personally i do not understand the reasoning for closing the gap. The TFI system produces plenty of spark. Just me could be wrong. I agree with Jeff 100%

How do you know you need more spark? Have you monitored fuel pressure during a run?

What the heck are you talking about? Batch fire is a term used to discuss INJECTOR firing.... injectors are either batch fired or sequentially fired. Are you talkin about a waste spark system? COP? CNP? Do you want to run DIS or EDIS?

I still think you have other problems, not a spark problem as others have said.

i dont think he knows jeff, the car as it has been posted many times before, wasnt running right when it was stock, and now its "modified" and still dont run right. Makes you wonder.. if they posts were a little more clearer and typed a little better we MIGHT be able to help you out a little better dude.
