I'm looking to get a hand held programmer for my 98 5.7 vortec. Im not interested in a Black Bear tune seams like to much of a pain specially being all the way in Saskatchewan. I'd also perfer a hand held programmer as I can check and clear engine codes as the shops around here charge one hour shop rate for five minute scan local GM dealer is now at $150/H shop rate. I'd also like one so I can change tire sizes if change out to bigger tires and id also be able to change some shift points. Who makes the best one ? And any experiences? I'm not to concerned about power gains it's a old truck with 340 000km on its gutless I know that and I'm fine with that.
