Umm, Never...especially when my stock motor on my car (with accompanying teeny tiny rims) goes blowing by a similar car with loud pipes and 18" rims.
(I found the TH fix to be highly annoying, almost as if the car actually revved down TOO fast.)

"A must do for the 95-97 Duratecs. Driveability is much improved with the fix."
Response: Nope.
(I commute 80 miles per day and drivability definitely did NOT improve.)

"The easiest way to reset the engine computer (PCM, or Powertrain Control Module) is to pull the #4 and #11 fuses from the power distribution box under the hood. It is located between the battery and the fenderwell. Leave the fuses out for 1-2 minutes to clear the KAM (Keep Alive Memory) and the computer will relearn all its settings. This is absolutely necessary after performing a performance modification."
Response:
If the computer is a learning unit, then it should be continually learning, and not cut off at age 14 like a teenager that thinks he/she knows everything. While there may be evidence supporting the computer MAY learn a "modification" to one's car more quickly if they reset it, it will most probably "learn" the modification pretty fast, anyway, attempting to get all functions back to an acceptable balance.

"Bret, if you don't like the above statement as proof, ages ago someone posted the approved Ford relearn routine, which is about a page long. Of course, I don't have a link for you. Maybe someone else?"
Response:
Wow! (I can write a page of code in about 2 minutes.) If the computer 'relearning' code is only a page long and the CPU in the ECU is anything near modern vintage, then the CPU would run through that code, making adjustments and 'learning' several HUNDRED times or more in the first 30 seconds of driving alone.
I find that most 'modifications' do little, if anything, to improve performance unless they are applied with commonse sense and a balance of other modifications are also applied. (for instance a less constrictive intake / headers AND exhaust will probably make SOME difference but merely removing the resonator will not do much at all.) It does not suprise me in the least that some folks have measurable performance LOSS whilst installing the throttle hang 'FIX'.
