Ive used a couple of different types,,,, the holley,,,,,a good little unit SDS (simple digital systems) and then the fast system,,,I used the fast system on a combo very similiar to yours,(85 tuneport 305),,,,,,,,IMO,,the fast is expensive BUT it does great,,,,I like the `idiot mode" the fast has,,,you tell it what you want and it will do it( A/F ratio),,,OR tuning can get high tech if you want,,,tuning each cylinder for individual timing and fuel,,,,I just used mine in the bank to bank mode

My SDS system was far less expensive BUT you had to make all the changes,,,,,at the time,,,it ran on a set program and didnt take readings from the O2 sensor,,,,it also had its own hand held programmer and didnt need a lap top like the others


if budget wasnt an issue,,,I would go with fast
