My father in law just changed his injectors from 36#s to 60#s. While waiting on his new chip, he started it with the old 36# turbotweak chip and it idled fine. He borrowed a friend's 60# hotair chip and it idled too high, like 2000 rpms. He just put in his new, correct 60# turbotweak chip and it idles too high just like the one he borrowed. Anybody have any ideas?
