car breaks up around 6k rpm

[whitedevilstealth]

Just put 19t's on my stealth. Now it breaks up real bad at around 6k rpm, I replaced the plugs and checked for vac leaks and cant find any. Could it be the car is needing a tune because of the new 19t's, went from 13g's, so there is a lot more air going through. What else could it be?

New plugs...it's spark blow out man...what did you gap too?

[DuTTch]

what kind of ignition system do you have?

[whitedevilstealth]

.032 brand new ngk iridiums, msd wires. It did the same thing with my ngk coppers gapped to .032. That's why I changed the plugs out.

Should I get blowout at 16.5 psi?

[dpartinvr4]

try .028 and see if that helps...it's free so it's a good place to start.

Might want to get a HKS DLI.

Might want to get a HKS DLI.

Do you have one? If so, did it help with spark blowout at high load?

[whitedevilstealth]

I cant afford to get one of those. why would it do it with the 19t's and not the 13g's?

Going to have to get back to you the next time I change the plugs. I really want to do some testing with it to see how much it works at different plug gaps.
