i have a 97 sierra 350 vortec i want to know what the best computer programmer anyone out there has had the best luck with thank you

 

Pretty sure everyone is going to tell you to get a custom tune. Much better results and they are cheaper.

 

How much are you willing to spend? How many miles on the motor/tranny? Any bolt ons done to it so far? Give some more details friend as to how much you are willing to put on the truck. Im sure you know about exhaust or intake but there are many more. Like camshaft, hotter ignition, bigger ratio rockers, ring and pinion, of course a custom tune. The money you pay for a handheld tuner like Hypertech would rather be worth using towards a more in depth tuning. Just check out this website for some info...http://www.gowheatley.com/
