Performance, Brainstorming & Tuning Talk about modifications, or anything else associated with performance enhancements. Have a new idea for performance/reliability? Post it here. No idea is stupid! (please use Detailing and Appearance for cosmetic ideas)

Ran a test the other day at WOT to see what kind of air I was pulling. TunerPro recorded .53 grams per second at 5400 RPM. Not exactly sure what that means.

On another note, I found the reason for part of my problems. I have at least one burned valve.

Getting replacement low mileage (85k) heads in about a month.
