You should consider air inlet filters, because my air intake on the tempaflow is pretty dirty. My dcs goes off if I hold WOT too long, things heat up under the hood and the tempaflow leans everything out, thats my theory anyway. If you don't go lakeracing much this is a great product when you are jetted properly. I'm going for a vari-flow next season so I can alter the fuel flow on the fly!
