ECM TUNE FOR 83 CFI

Looking for someone who can tune/program ECM for 83 TA w/CFI. Changing the 305 CFI to 84 Corvette 350 CFI. I know 83 ECM is non-programmable. I need 87 and up ECM programmed for 84 VETTE 350 CFI engine. Any help would be greatly appreciated.

Re: ECM TUNE FOR 83 CFI

'83 CFI f bodies use the same ECM as '84 vette-just use '84 vette prom and it should work.VSS pulse might be different for vette ,but might not cause a problem.I have '82 setup and '82 vette prom works great-same cable drive speedo with '82s
