Just installed a R D logics pipe onto the 2.5 made to increace bottom end.With the factory settings the tranny does not want to shift into 2Nd gear. On second tank of fuel made 1/2 turn to adj. screw, starting to shift but takes 1/4 tank of fuel to make 1st shift and about 5 high speed runs before it shifts consistantly. Made another 1/2 turn to adj screw with close to the same results,shifts a tad sooner than the factory setting.Owners manual said not to tinker with adj. screw to much,but I would still like an eariler shift point since this aftermarket pipe produces so much tourqe. Any advice or tips would be greatly appreciated. Thanx in advance. Also what's the word on sway bars?

try leaning out the motor if its to rich it wont shift this could be your problem i had the same problem
