1990 460 Speed Density

[monstertrucker]

Bill,

first post from a newbie. I have a 1990 F250 4x4,7.5l, 5 speed zf,4:10 gears on 44TSL's, a mud truck. Engine mods consist of Hedman Headers,Underdrive pulleys, K and N air filter, BBK adjustable fuel pressure regulator (set at 41 lbs), a custom 3 inch plenum spacer, a 1 inch throttle body spacer, and timing set at 14 degrees. I have done an EGR and Smog pump delete as well. My question is would any of my mods conflict with the programing in the Pegasis Chip? I don't have the ECU part number in front of me, but I can get it no prob. The truck runs good, but I notice a miss under highway driving conditions (EGR delete?) and I tend to bounce of the rev limiter while racing in the mud. I would love to eliminate those two problems, and i would love an all out race setting for more power while mud racing. Is any of this stuff possible?
