[QUOTE="tktlwyr, post: 13417507, member: 92085"] Throttle body opens quicker boost comes on sooner. I'm not sure exactly what the table is you modify (I'm not a tuner, but I did sleep at a Holiday Inn Express last night). This is how Ford limits the power for the first 5 miles on the GT500. The supercharger bypass opens when you have vacuum (idle) and closes under boost. It's mainly just to give the pressure somewhere to escape when you let off of the throttle and prevent rotor damage. It does have an effect on boost, but the main player here is the throttle body. FWIW, an improperly adjusted bypass can cause a stumble. I know because I chased this a few years ago (my bypass was loose when my blower shipped from Whipple). Have someone operate the throttle and check the operation under the hood to make sure it opens under vacuum and closes when you goose the throttle. [/QUOTE]
