My GTX has a 3.25" pulley, SLP ram air, SLP loudmouth exhaust, 160 stat, NGK TR6 plugs, and a 2.5" pipe in place of the cat/u-bend, and I always run 94 octane. Sometimes I have a problem with it nose diving at 93+mph. It feels like it shuts down. Sometimes it doesn't happen. I even added 5 gallons of 112 octane, and no luck. It did it before and after the cat/u-bend delete, and yes, I do have an O2 simulator. I am thinking it is lean and I need an AFPR. Any ideas?
