I used an efi tuner on my old silverado ss, but he does not do diesels...anyone in the dallas area that y'all know of?? I had 15 guys show up at my place and this tuner to custom tune our ss's. We found each was different and were tuned accordingly...I am wanting the same on my truck instead of a "packaged" tuner box.
(I have a particular power sucker that needs put in his place...Please help!!) thx..

You might be ale to find someone here that would be willing to forward that guy a tune to load into your truck for you.
