Throttle body bumpstop mod, Question
Throttle body bumpstop mod, Question when doing the bumpstop mod it says you need it at 4.7 volts. What happens if you are over or under? Just wondering because I didn't even check mine.

if you are under the 4.7 volts you are safe. if you go over the 4.7 volts the car will not run right. you are letting in too much air

. It just throws the SES light on. Essentially, depending on how much you over grind the bump stop, you're actually undoing the good you just did, since it allows the TB blade to go past 90 degrees.

You use a multi-meter to check the TPS voltage untill it's AAAAAAlmost at 4.7 volts, then you stop grinding the bumpstop.
Most cars won't feel a difference, but some cars came really fubar'd, and only opening like 85%.
