Need Help!!

I have a 02 silverado 5.3 4l60e with a cold air intake, throttle body spacer, comp cams 228/228 .588/.588 112 lsa and i just bought a jet dynamic spectrum tuner and cannot by any means get my truck to shift or stay running. i do not have any kind of dyno shop anywhere close to me and need help! any advice or links to website to help would be much appreciated.

I would call nelson performance and they could send you a reprogrammed pcm with all of the specs you need.

is the cam you have (assume you installed it) rated to work with your truck / fuel injection setup? You can spend a whole lot of money on this stuff without much gain in real power. You might consider putting a new stock cam in engine. Just swapping the camshaft will not show significant gains in an otherwise stock engine. Getting something like that to run right is an expensive challenge.

Thats a pretty big cam to get to perform in a truck with stock gearing and convertor, I am sure low and mid range torque has been affected, as well as idle vacuum, are you sure you have .588 lift? How about exhaust, stock? Any check engine lite on?
