slight stutter under light load

[camarojoe12]

Brand new opti,coil,plugs,icm. I contacted madz28 the guys said with it running cooler (had them command fans sooner) it will run richer. I am going to use the sniffer on the inspection machine to get readings on the exhaust to see how rich or lean it is. Any body suggest adjustable FPR?

I would have thought that he would adjust the AFR for cooler running temps. I wouldn't use and adjustable FPR to lean it out because that will lean it out all across the board. A dyno tune would be best or do some data logging and get it adjusted. Otherwise you'll have to live with it.
