If you read PowerChip's SRT-6 promo, they are mixing up the SRT & the NA Xfries - the hp/tq figures on the last page are for the NA Xfire, as is the "dropping the clutch" testimonial.

Since the SRT-6 actually produces 349hp, and the 93 octane chip costs $690 and gives you 353hp, that makes it $172.50 per hp rather than their claimed $30.

If their promo literature is this badly done, I would not trust them with my car.
