Thanks for the info. I might have to think about switching it out then.
I see you are in Jacksonville. That's where my stang was evidently originally built. The owner stated he had the motor done by a company called Tachion motors ? Does that happen to ring any bells?
Just about 20 minutes south of Charlotte, NC in a town called Lake Wylie (South Carolina)
Just searched the forums for a real good tuner in the Carolinas and found one highly recommended. Unbelievably - they are only about 10 miles from my house - now that doesn't work out like that very often
