Hey guys i have an evo 8 tuned to 28psi- i hit 30 yesterday due to the cold weather- In full boost the ignition starts to break up as if i need new plugs--maybe i do- i changed them before the tune

i have a coil pack setup wich i was told should fix that problem
-any suggestions would be great!!

The question is, did you re-gap the plugs to a smaller gap? Running more boost normally means you'll have to run a smaller gap.

What did you gap them to?

I had ignition break up as well but i had the HKS DLI system. I had to switch over to a coil over plug setup and never had the issue again. Plugs can be an issue as well.

Sparktech has a new setup out for more daily driven cars that is proved to hold up to 600-700 whp....

Might wanna look at going coil over plug to truely eliminate the breaking up issues at high boost.

You just need new plugs and gap to .018

I would say plugs are the cause as well. Ive seen them work to ~33 or 34psi no problem.

If your gonna go COP, try the Spoolinup.com kit. I have friends running it and they seem to really like them. Its a lot cheaper than other kits on the market too.

We have used stock coils to 650+whp and 42psi.

The plugs are not set up right.
