ok guys i took the car for a pass and i was seeing the blm's at 144 at WOT adn about 136 at idle. that indicates im running lean so i turned the FP up a pound or 2 and the car felt sluggish and everything. so i turned it back down to 39ish with hte line off. the testa chip for the 42.5lb. inj. calls or 38-41 with line off at idle. waht could be causing this lean conditon. i have no knock up top and the car pulls harder with the lower FP? any idea?
