Im thinking you are running really lean. be careful you dont hurt your motor. im not a tuner but thats what it looks like to me. good luck and enjoy your car after you get it right.

Brain then what else do you think it could be asides from a tune problem? Cause I have no clue. I get a back fire from time to time at low RPMs It smells like its super rich but on the Graph it shows super lean. The only thing wrong I can figure out is a small exhaust leak off the Y-pipe. It burns gas like its rich a whopping 13.2MPG.
Its an FFHP 6.0 Stroker 408
PRC 6.0 stage 3 heads that where tounched up a tad by FFHP
TSP Gaint Cam 248/252 611/613 on a 113LSA
Hooker 1 7/8 longtube off road Y
SLP underdriven
its a SpeedDensity car
MTI clear lid
MSD 8.5 wires
NGK tr55 plugs
Now running Mobil 1 full syn
always 91 or better gas
stock rockers
42lucas injectors
Ractronix 255l system
6speed car
Oh the exact details for the motor I didnt get cause of what happend with FFHP I know it was built for spray. But anything else I am cluless I never got my blue sheets or anything
