Well, you can't really compare a stock anything to a tuned competitor. This particular tune seems a little unrealistic as a daily since you need to feed it E-50, doubt most would want to fiddle with the mix at every gas stop. Then there is the issue of you just voided your warranty.
It is pretty cool tho that they got that much of a bump in HP/TQ with just a tune & gas. Would be interesting to see what one of the Mopar tuners could do with the SRT (or even an R/T) given the same parameters.
