I was told that CMR tuners can tune for performance mods ,even boost
Factory ecm would be a lot cheaper ,even with hotwire harness, under 2k complete





That's true, but consider the evolutionary nature of the average hot rod. Intial stockish build, then a couple years later cam and heads (time for another tune). Couple years later, stroker kit (retune). Couple years later, supercharger (tune again). CMR does work, but it's not cheap. IMO it's best use is in a newer modified car, not an old car converted to the newer engine...but that's just my opinion.
