well, im looking to tune my truck to let the exhaust and intake perform to full potential...looking for a little better gas mileage. And, I know hypertech can increase the speed limiter (i'd like it to compete a little easier with some newer fullsizes, and mainly to have that edge for freeway for passing).

CIGAR LTR fuse...thanks brah.

A hypertech won't help fuel economy, because they don't tune part throttle. I would consider a mail in tune, like pcmforless or something.
