I do have an AF guage, but I don't think it is telling me what is really happening. My car, under boost bellows out black smoke from the exhaust.. So I know it is running way to rich... Hence the fouled out O2 sensors. I know that on the Vortech RRFPR, you can adjust the ration of fuel to boost.. right now it is at 7:1.. I think I could even drop down to a 5:1 ratio since I am so high in elevation. (4500ft) I have talked to people that have the same kit that I have and they have no trouble, so I don't know what the hel is going on... I am getting tireed of my car pulling all of the timing, and most of all I am getting sick of the damn thing bogging, and stumbling. anyone else have any suggestions why my car is doing this???? I have checked the codes on the CEL, and I always get p0108, and p0130.. I fixed the map sensor code, with my VC2, but I don't know why I keep getting the O2 sensor malfunction code, with a new o2 sensor help!!!!!!!!!!!!!!!!!!!!!!!

If you have a fuel pressure gauge, check to make sure pressure isn't too high both at idle and during boost. I have read about the newer RS (MAP) usually need the SVX or adjustable FPR along with you RRFPR; you have both installed?
As for running too rich, have you tried 1 range hotter plugs? That may help burning off some of the unburned fuel.
Running any engine management also?
Good luck tuning.
