programmer?
 

what programmer do you guys suggest for my truck?

it's a 99 chevy silverado 5.3 4x4 flowmaster k&n

The only programmer worth $.50 is the predator. i would spend the money on a custom tune from Nelson performance or blackbear performance. custom tunes are 100x better than programmers.

Predator, custom tune are better for "get it and forget it". You get it done right the first time, but have to pay to get it updated in most cases if, say you get a cam or something. Predators are cheap, I hear bully dogs are pretty good, but if you got the cash and don't need to change anything on your truck afterwards, get a tune.


Go onto diablosport.com and view the GM forum. There is a lot of info there on tuners.
