A quick question, I've done the AFM Mod as specified and other than eating up lots more gas it doesn't seem to be giving me more preformance. I understand that it'll run richer with the mod but my digital dash fule gage dropped a full two bars after maybe 30 min of driving, admittedly it was at high speeds ;-) but still, gas is $1.60+ so is it worth it?I've got a K&N cone filter on it with the stock piping. I moved the spring forward 4 notches and that seemed to help but I also was getting a strong gas smell and the exhaust smell seemed stronger also. Since then I've moved it to two notches past stock and it doesn't seem to help either problem. I've got the stock cat. and 2.25 exhaust with a magnaflow high flow exhaust muffler. Anyone else with this mod? How has it worked for you and whats the supposed difference in performance?
