look at the dyno. stock gs400 is 300hp and 320lb-ft... this is some serious supercharge. and SRT actually has a total of 4 stages, this is only stage 3. i can't imagine about the 4th stage.
now with all these results, imho i think the sc from comptech isn't that amazing at all. you still pay the premium but the gain is marginal, not to mention you need a new tranny whereas in the gs400 the tranny is strong as hell
