Hello
I have an 01 cobra with an eaton swap and I feel my tuner doesn't really take the time to get the car right he just tries to make as much power out of it safely. I have a Steigmeir Stage 8 port with dragon port matched plenum and dragon throttle body with Venom cooler and a 10 pound lower and I think a 3 inch upper id have to go measure the upper to make sure. I also have the JLT 12" high boost CAI and that's where I think my problem might be coming into play. The main problem I'm having is my idle. Ive heard that a lot of people with these dragon throttle bodys have a surging idle. Before I had a JLT high boost CAI I had a BBK CAI with a SCT BA 2600 MAF. And since ive installed the JLT high boost CAI I put the SCT BA2600 sensor into the JLT tube itself, no more need for a MAF housing as the JLT tube has a slot directly in it for the sensor itself and ever since then I have had an idle issue it bounces back and fourth between 1000 and 1400. Also since installing the JLT CAI ive had a po171, p0174, p0420, p0430 and a p1506. I have access to both the advantage 3 software and the sniper software I got them just recently which i still have to go to dyno classes so any help with correcting my idle issue would be greatly appreciated I do believe setting up a good MAF transfer function might help or anything that has to do with the amount of air flow coming through the intake or maybe iac duty cycle or something. I am aware that ford calculates their MAF transfer functions with a flow bench but I don't have access to one so I figure their has to be some kind of equation to calculate maf transfer function maybe based off spark, load, torque or something. If you need access to any of my tune or datalog info let me know. Also another problem I am having is when my car is on the dyno and it gets to 18 pounds of boost around 3500 to 4000 rpms it drops to 14 and stays there and I don't think this is belt slip so if anybody has any ideas on that it would be greatly apprected as well. Sorry for writing a lot and writing more then one subject in one thread.
