I have a lagging/backfiring conidtion that I was wondering if someone could help me with. Here is what is happening: I have notice that like when i am accelerating hard on the highway in third gear(also does it in other gears) at WOT it hesitates, lags and has been backfiring some.(only does it under WOT) I was unsure what the cause could be. Here is what I have done to the engine.<p> Vortech R trim supercharger(10 lb pulley), trickflow twisted wedge heads, lunati cam, 1.6 rockers, edel RPM u/l Intake, 70 mm TB, 73mm MAF, 30 lb injectors, Vortech FMU, MSD BTM(1/2 degree), 14 degree timing, AUTOLITE 3923 plugs(.35), BBK longtube Ceramic headers, etc.....I WAS WONDERING IF ANY ONE HAS ANY SUGGESTION ABOUT WHAT COULD BE CAUSING THIS ACTION. Could it be to much gas and it isnt all getting burnt?,to much timing retard?not enough gas?wrong fmu calibration?(PLEASE HELP ME SOLVE THIS PROBLEM so i can quite worrying about it....One more thing, will it hurt to run with the BTM at 0?(i have my rev limiter set at 6k and have never seen more then 8 lb of boost).
