| How do you say that. A pretuned ECM with a DSP5 gives you 5 tunes in one ECM. The tuners on this site have better tuning than any canned tuner. The pretuned ECMs are for people that dont want to take the time to learn EFI or dont tinker with things. If they dont plan on doing many upgrades, that would be their best bet. No sense in spending the full amount and not use it to it's full potential.
