I only have one prob with the SCT , some have had problems with switching tunes:dontknow: somehow the files get corrupted ro the tuner itself gets fumbled up sometimes
If a person just wants a touch more performance and isnt goint to switch back and forth, then personally the flash would be best
but if your gonna be adding back and forth then go iwth the sct
