[QUOTE="SecondhandSnake, post: 15440672, member: 116684"] Yeah I agree; with the MAF configuration I'm using if the ECM actually believed that it would be jumping between no flow and around 96 lb/hr of air. No way anything would run with that kind of data. I am logging MAF counts (maf_cts), not the 03-04 Cobra MAF counts since I have a GT with a GT PCM and wiring harness. I was honestly contemplating a flow screen since previously the idle would vary 200 RPM, but I think that can be chalked up to the tune being too lean down low, leading to lots of misfire and stumbling. Now it's rock steady, which I'm surprised at with the large housing diameter and poor geometry. If nothing else I wanted this information out there for when some other poor soul is seeing this and tearing their hair out. [/QUOTE]
