well i bought mine when matt had some refurb models so i got a huge discount. other than that theres no other way getting around whats on the website. Ive towed my boat with the 250 tuned and it never saw 900 degrees, this weekend im headed to the ranch and ill hook the gn up and use the 250 tune. ill report back about temps on that. just be smart about how you drive and youll be fine with the higher tunes.
