mrp699 Posted September 15, 2004 Share Posted September 15, 2004 Hey, Just wondering i got a 94 R33 GTST, Full exhaust turbo back no restrictions but a high flow cat :wassup: K&N Filter, Turbo smart single stage boost controller etc... As you can see nothing major as far as mods. Running the car on 10-11psi at the moment and it goes good. When i run her up to say 13psi its just misfireing and probly going slower. Any ideas?

Sydneykid Posted September 15, 2004 Share Posted September 15, 2004 Excess airlfow protection by the standard ECU. Do a search, there are plenty of threads on that subject.

Guilt-Toy Posted September 15, 2004 Share Posted September 15, 2004 Yep. take your spark plugs out and gap them to .6. That will fix the problem. Link to comment https://www.sau.com.au/forums/topic/51152-boost-on-r33/#findComment-1013518 Share on other sites More sharing options...

Yep, that'll fix the missfire and at 13 psi it will then hit the excess airflow protection, if it hasn't already. I was just being economical, saving another post later on.
