Performance tip for throttle body?

[ricematthews]

Has anyone out there heard of the below described performance tip?  I saw
this on the site www.grandtouring.com and wondered if this had any merit.
Thanks,
Mark

"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"
