ECM help

[S.Hitt]

Is it worth putting a turbo tweak chip on an 84 ecm? I want to keep the car mostly stock but be able to run 91 safely. Already have a FPR and gauge. I don't want to have to change MAF and other things. However, if I have too, I am not against it.

Just figured out that this rebuilt ecm shows to be for an 84. Also, it has a hypertech chip for an 84 ecm. Has anybody had luck or even use a hypertech chip?
