Bbk 85mm TB on 2012 Ford Mustang Gt 5.0L

There is no tune that can fix a faulty TB actuator that causes his engine to idle at 2000RPM and throw a P0507 code unless he turns it off and on a few times. Tunes are to maximize the effect of mods and fix A/F ratios so you don't have a lean condition that can damage your engine. They are not his problem and his idle problems will return if he uses that TB no matter what.

There are many potential causes of code P0507.

• Intake/vacuum air leak (most likely cause)
• Faulty Idle Air Controller (IAC) Valve
• Faulty power steering pressure switch
• Faulty electric throttle control actuator
• Improperly adjusted throttle cable
• Carbon buildup on the throttle body

Is that the black plug in with red tab below the TB ? If so , wouldn't it be a issue with the stock TB as well ?
