I cant boost above 17 psi on my current gr40r setup without running into ignition problems. My results so far at the 17 psi have been 428whp and 368wtq. I was just wondering what numbers some of you guys have gotten on the stock ignition setup or if anyone else has run into the same problems. my ignition has around 84k on it.

 

I've run 41 psi stock coils. Autronic ECU. Denso IW plugs. Two or three steps colder from stock. Can't remember. I do use Ralliart plug leads but doubt that helps much.

Are you on an AEM. There is a thread about AEM's dwell settings for the coil being all messed up in their base maps. Check it out.

 

Ya im running aem, stock coils and new stock plugs.
