Actually you will be ok.  What type of FRP did you get??  You need an
adjustable one like the one cartech makes.
My car did that too for a while.  I tried an assortment of things before the
cartech.  I had a fuel pressure gauge and air/fuel meter installed to see
what is happening.  You have to have a FPR that adds X amount of lbs of fuel
pressure for every pound of vacuum.  It is a tedious task to get it right..
but that is what tuning is all about.  Be careful.. don't let your car buck
too much... I learned that bucking is actually the car detonation because
there was not enough fuel to allow that cylinder to spark.  That is much
much worse pinging.. If the VW blocks were not so strong... the engine would
have been gone on the 1st buck..8(
	On another not.. the car that GIAC has running the TBody deal.. well the
throttle body is not actually bored out, but the ramps removed.   I think
that project may not hit the shelf anytime soon.  To fix it, you basically
have to make the PT map so rich that you will eventually set off an engine
check light.  An easy fix is the adjustable FPR.  that way all your maps
stay the same, including the PT map, and the FPR dumps more fuel only when
needed, not thru the whole map.

You should not have bored out your throttle body.  It is allowable on OBD I
vehicles but not on OBD II cars.  Garrett Lim of GIAC was working on a chip
to
overcome the bucking and driveability problems associated with boring out a
OBD
II throttle body.  You will need to ascertain another stock OBD II throttle
body.
