TB bump stop mod (TPS reading)? Hey guys was looking into a ported TB for a buddy of mine and was wondering if the bump stop modification on a ported stock throttle body will mess with the WOT reading being the the TB plate is actually opened further now then before and if so ,,,does it effect anything?

Properly done, no. Bumpstop should be dressed
until the blade just pulls to center, by the ruler.
Not by voltage or % readings.
If you go over 4.75V at WOT on an A4 car you
will get short-shifted even if it's not long enough
to set the code.
