I just finished installing an MSD 6AL ignition and TFI Blaster coil with the Ford/MSD wiring harness. Anyway, after hooking everything up and starting it up I noticed a little problem that didn't exist before. When I punch the gas pedal it hesitates before revving out. It's like it bogs for just a split second and then revs normal. One problem might be that I grounded the MSD box to the frame and not to the battery negative like suggested. Would that cause this or is it another problem? Any ideas? Thanks!
