Performance tip for throttle body?

[JShadzi at aol.com]

Ok, this guy is really confused, 100hp by opening the same throttle body a
little sooner???  Its not like airflow into the motor is increasing, the
final WOT condition is exactly the same.  What he is doing is basically
re-calibrating the throttle cam on the throttle body to open the TB more,
sooner, but not actually open it more overall.  He is feeling that what used
to be 1/2 distance travel with the "gas pedal" is now at 1/4 travel.

If you do this, you will make the on-off throttle transition more sharp, and
inevitably, more jerky.  Everytime you get back on the gas the car will lurch
and the motor will snap back and forth on its mounts, not very pleasant IMO.

Anyway, you can try it, but its not worth even 1hp.

 "I WOULD LIKE TO SHARE A TIP WITH AUDI ENTHUSIASTS WHO LOVE THE EXTRA POWER
 WHEN THE SECOND LARGER THROTTLE KICKS IN. PICK UP A SCREW AT THE HARDWARE
 STORE FOR 5 CENTS THAT HAS A 5/16" OR 3/8" WIDE CAP WITH A SCREW LENGTH OF
 ABOUT 1/2" AND DROP IT INTO THE SLOT ON TOP OF THE THROTTLE LINKAGE WHERE A
 SMALL PIECE OF METAL HAS TO TRAVEL ABOUT 3/8" BEFORE IT HITS THE SECOND
 THROTTLE ARM. BY BRIDGING THIS GAP WITH THIS SCREW THE LARGE AND SMALL
 THROTTLE S OPEN IMMEDIATELY WHEN YOU GIVE IT GAS AND FEELS LIKE ABOUT 200
 HP. I DONT FIND CHANGE IN GAS MILEAGE BUT THE CRUISE CONTROL IS NOT AS
 SMOOTH AS IT SURGES SLIGHTLY AND ON LONG TRIPS I JUST POP THE HOOD AND PULL
 IT OUT AND PUT IT BACK IN THE CITY. WITH THE SMALLER 5/16" SCREW I DO NOT
 FIND IT A PROBLEM ONLY WITH THE 3/8" WIDE CAP SCREW. THE DIFFERENCE IS
 UNBELIEVABLE 100 HORSEPOWER FOR 5 CENTS.DOESNOT WORK FOR SOME TURBO AUDI
 MODELS WHICH HAVE NO GAP TO PUT THE SCREW AS IT HAVES DIFFERENT LINKAGE"
