Even the so called "custom" tunes on a SCT are not custom.
They are off the shelf programs generally tailored to your mods.
Cars are different from the factory (hence ECU codes),
and therefore when modded they do not get the exact same gains and do not end up with the ECU adapting in the same way.
(Thats not a real clear statement, but it gets the point across.)
A true custom tune is done on the dyno.
Even ones done from a dyno sheet (like I did) aren't as good.
Bang for the buck, SCT with 3 programs is the most flexible option.
But unless you need multiple programs a single program chip is more than adequate.
My plan is to get to ADC when finished and have them custom program my Superchips flip-chip (2 program), one for street and one for nitrous.
