Well i have had my car for a few months and it only had the paxton novi 1000 kit with the fuel pump and injectors that come with the kit. I am running the 6 psi pulley that it came with. Well i strapped it on the dyno today and we started the pull, it was running a consistent 11.8 afr up to about 3k, then it went a little over 12 afr and then dumped fuel and the afrs shot down off the graph (past 10) then at 4000 they started to shoot back up and we stopped the pull at 4500 when the afrs were right at 14.0. I am pissed that paxton/diablo cant provide a better tune for their crap than this. Anyways, even with the tune and stopping where we did, i put down 315hp/345 lb ft. Oh and also, from 2500 rpm and up, my fuel pump was at 100 percent duty cycle, and at 4500 my MAF was almost pegged. im pissed. paxton blows
