Is the car running poorly? Reason i ask is because 93s with long tubes can have problems with the O2s not staying hot and can cause LOTS of tuning issues! (ask me how I know!) So I would suggest going to someone that has a wideband as you can't trust tuning off the O2s. You may need to convert over to heated O2s.

Regardless of who you get to tune the car, note that you cannot use a tune to adjust the speed-O. you will need a recalibration box to get the speed-O/odemter working properly.
