it depends on what you want to spend and what you want to do hypertech is a lot for what it does but you can get used ones on ebay cheap it isd worth it dnt buy new bully dog kits are nice too

The new Crane Tuner is super. Just got one for my 03 5.3 Tahoe. Made a real nice performance increase. Best of all it has tuning built in it for several different RV and performance cams. It also has tuning for superchargers, high-flow injectors, headers, can adjust idle speeds, all the other stuff that Superchips, Hypertech, etc have. I drove a Tahoe at Vinci High Performance in Orlando with a 216/224 Crane cam,1.8 ratio rockers, Magnuson supercharger, Bassanni headers and exhaust. When they first fired it up it idled rough, had a hesitation off idle and had what I thought was poor low-end torque. They hooked up the tuner and in 5 minutes that thing idled like a rock. It drove like a dream with tons of low-end. Without any exaggeration, it ran like it had a well built 502 under the hood. Ordered my tuner on the spot from Vinci's. Their going to do my cam change and exhaust in a few weeks. Try it you'll like it!

 

I would go with Bully Dog I was watching trucks and they installed one it was realy cool.

 

I saw that same thing on trucks it looked bad ***
