I have a 91 900 turbo convertible, it has Swedish dynamics APC, 30# injectors, SD 2.4lh chip, the car boosts all up in the red but the boost kicks back and dances around the middel of the red. when that happens on a cold day like these days , it feels like if the car is misfiring, Does the SD lh chip removes the fuel cutout limit detected by the amm air volume?. is a 300 ohm resistor needed to work with the upgraded chip?. or am i getting knock because the air is too cold (*more 02) than the chip programed to handel. over all when i installed apc, the injectors and the chip, i added a spring on the waste gate in order to increase base boost which is now set at approx 8-9 psi. Am i supposed to set the basse boost to 10+ psi in order to get a steady 20psi of boost.?
i want to run. 20-22 psi with steady boost and good fuel supply. so again, 1) 2.4 lh chip+ amm resistor (yes or now)?,, 2) base boost settings what is recomended for save 20-22 psi?
