Hey guys, just need some opinions on buying a chip for my 99' 4.3. Been looking around but can't really find much surprisingly. If you could suggest one and why it's good that'd be awesome

 

A "chip" = "Don't Do It Rambo!" All those chips you see on ebay etc are garbage. If you want to get the most I'd say check out PCMFORLESS.com or get a Bully Dog programmer or Hypertech. Any good company that reprograms or programs a PCM for you is the best way this side of putting it on a dyno. Some even have info collectors that plug into you OBDII port & record your driving style & they make a program based on that info.

Search in here for chips, PCM mods etc... change up the wording & read all about our experiences.
