Working on a truck used for sled pulling only. Problem we have is it has a full manual valve body and wonder if trucks in limp mode as it wont light the charger , single 76mm ball bearing, 350 horse sticks , 2400 stall . The truck wont rev over 2200 when in gear and seems to be under fueled
 
limp

the truck will light but only if allowed to roll out aways and when it does it still appears to be fairly under fueled, truck has dual pumps , udc tuned with a 2500-2700 us tune so there should be plenty of fuel , if sitting on the line it will just rpm up to a point and stop at 10psi no more
