My truck acts like it needs jet extensions, but I have them in there. This carb is a 950hp and worked great on my camaro with D3R, now it is in a S10 with P1SC and it stumbles in low and runs fine in high. Fuel pressure is up 28lbs, float level is good, white bowl vents are in. It only does this at the track when there is high traction, it will not do it on the street or when I bring it up on the transbrake .
Help please..
