question, 2nd gear im at 13 lbs with creep up to 15. 3,4,5 gear i get a heavy sputter when i hit full boost. it does not do it in 2nd gear. only 3rd+ when i hit full boost. i thought i was hitting boost cut because of the boost creep. my boost cut is at 22.9lbs. I have a Motorola 2.5bar map sensor. which should be good to 35lbs. (1bar=14lbs) if im correct. so i lowered the boost in 3rd+ to 16.5lbs with a creep to about 19/20lbs depending on temp. it is still breaking up and not going near 22.9lbs. what could be the problem? the weather is about 20degrees-40degrees outside. plugs? wires? weather? tune?
