i was looking to buy one of those flashpaq superchip tuners and was wondering if they really add some mpg. i got the 5.9 and drive from sc to pa often and u could only think of what that is in gas money. just looking for some sugestions and comments. thanks guys.

 

my sc 3815 took a dump on me a week after i got it and i am having a hell of a time getting superchips to fix it. it is stuck in boot mode, all they have to do is plug it in and pull it out... for some reason i dont have a secure enough connection??

BUT from what i've heard, the 5.9's are really corked up from the factory, and tuners really open them up. best bang for the buck

 

They'll never save you enough to pay for the tuner. They will however save you a bit here and there
