Before you throw alot of effort and money into a tuner I hope you have considered the obvious stuff first like1) A full on tune up with OEM and not aftermarket parts,2) 60 psi doesn't nessescarily mean that a motor with 290K and ??? hours on it is prime for a tuner/ chip. You may be better off with a fresh motor or a set of deeper gears or go back to OE tire sizes since everyone seems so fond of jamming bigger tires than OE on their Chevy's. I have found that if you are running a tuner/chip in a "work" truck and not having any issues it's because you are not running that truck as hard as it could be driven or you think you are driving it. Those damn chips in a well maintained,real work truck are nothing but trouble.
You're too funny!
Drop a new motor in? It runs just fine, but could use a little more low end grunt than the factory tuning provides. I believe tossing a $250. tune on it will provide just that little extra umph for towing.
