Just did the Bumpstop mod
Just did the Bumpstop mod Whew, that was a lot of grinding. Haven't driven it yet, but just wanted to say that you shouldn't use the stone type grinders but instead, one of these .

the BSM allows the TB to open to almost 90* providng that when you are doing you do not go over 4.71V..

now you need to make sure you are getting it fully opened.
Pop the hood and have some press the gas pedal to the floor while your looking at the TB. Make sure the car is off too. If it is not hitting the bump stop, your carpet behind the pedal is in the way.

i dont know if you are talking to me. but this is what i did. stock was 4.43V. grinded it to 4.67V then i had a friend go to the car floor it and it read 4.67V. but i never really felt a different in throttle response :whoknows:

start grinding again.. or take up the slack in the gas pedal

i personnly did not have to adjsut the cable and i dont think that the seach feature works anymore.. jsut make a thread about it
Yea there is an adjustment, well kind of, just add a zip tie or two on the cable after it crosses through the pedal, so it will take up the slack. This way you can get WOT without it really getting close to the carpet. Just make sure you dont pull it far enough where it opens the blades at idle. 
Just did my BSM and it wasn't the carpet that restricted mine it was that TCS/cruise control loop behind the battery/on fender well that kept it from making my mod @ 4.65v. Take off cover and twist it by hand and you'll see. So I disconnected my throttle cable at t-body and wound it up 2-3 turns to "shink" the cable. Idle will adjust itself. And yes I can feel SOP diff.
