i brought my car to a reputable shop to have my apexi safc2 installed. after install when they were gonna tune it the throttle reading said 33% at idle and would stay at 33% even when applying gas. they told me the throttle position sensor could be faulty or perhaps the wiring. has any1 heard of this issue while tuning? its also fumey as hell due to not being able to tune and sputtering and shooting white and black smoke while on boost. help cause im gettin frustrated :gtfo:

well i mean why would it read 33% at idle and stay that way even while giving it gas? what could that possibly be?
