Be careful about programmers. Most have all kinds of power settings, but many will say only to tow at a certain level for towing.
I have a Hypertech Power Programmer III (older version of their Max Energy programmer) When I had my gauges installed, the diesel tech said even with the Hypertech, he wouldn't tow on the top setting. (Hypertech says you can).
Also a general rule of thumb is to keep your EGTs at or below 1250* for sustained pulls. Above that for short bursts is not an issue.
If you're going pull that heavy, I'd definitely get gauges. I have the Autometer Z-series EGT, Boost and Tranny Temp. I have found them very useful while towing my 5er. (12K GVWR)
For something like this, definitely do your homework. Be as well informed as you can when deciding to programmer or chip.
Good luck in your search - It's half the fun!!!!
