Hello..so i have a 94 sierra 5.7 TBI and would like thoughts on smog equipment. Would it be bad if i were to take off or eliminate some smog equipment so my truck can run better or will it make it worse?
get rid of it! it does take energy away from the engine....with age they can seize and burn up the belt! it happened to me. when i removed the belt, the car picked up some power! i still passed emissions...
