Hey Mark,
Check with Zoom This (Bill) about a dyno tune - he told he that he has a lead on a dyno tune place in the East Bay with which he was really happy.
Another lead for a dyno would be at Apex Motorsports in Santa Clara - they focus more on late model mustangs (

Last, you might want to talk to Byron Race (he posts here wrt his Cobra build), as he's #1 in the area of tuning late model mustangs (chips) - I don't know if he tunes carbs...
Good luck,
Randy R...
