ok so here is the problem, we have an 00' firehawk, it has the 500hp head and cam kit (.576/.571 lift cam) installed, SLP long tube headers, dynamax bullet mufflers, lots of suspension and frame parts, LS-X intake, electric waterpump, 90mm throttle body, 36# injectors, moser 12 bolt, 3.73 gears, new fuel pump, smooth bellow from slp, bigger mass airflor sensor, 4000 stall converter, rossler built 4l65e, and finally a set of M/T et streets, our problem is such, car is running 12.1*-12.6* at 112, the shop that did the tuning never got it to idle right (weve been trying with them for over 2 years now) the car doesnt wanna run the numbers we know it should, and we need to get the problems fixed, we were looking into buying ls1 7.0+ for $2100 and were willing to go to that extreme, we need the program to work finally for us. were not quite sure what the problem is, we can start assesing with you piece by piece and are willing to send the ecm to get re-programmed if need be, thanks

not exactly sure what you mean by this? What kind of power did it make? What did it run at the track?

Xtremes10

it made 389 rwhp and was running at best 12.2* at around 112 mph

We need details like flow numbers and cam duration/lsa on the heads and cam to help ya out. Also those aftermarket MAFS suck and remember that the bigger rear will eat a bit more HP than the old 10 bolt and the big *** stall with eat more hp too although it will help ET.
