Put a 03 4.3 engine in a 98 Blazer and would like to find a person or company that could look at tweeking the programming on this Blazer. Driving a couple hours to get re-programmed is not out of the question.

Thanks

 

You could look into PCMforless or Wait4meperformance.

 

Getting a jet DST is probably the simplest. Will let you do full programming of PCM including vin changing. Costs about 475$ list but you can find em as low as 325$ currently.

Or... Drive to Oregon and I'll help you out, lol!

Good Luck!
