2004 Chevy Suburban 5.3L

Post by SeaRay45db »

Just got my Trinity 1000. Bought it for when towing, and any performance would be great.

Which program would you recommend or is this going to be a custom tune?

Really, so neither is better than the other for towing a trailer into the mountains? Would you recommend doing a custom tune?

Seems a little to simple I guess.
