William, Is your truck 4x4?? If so, Leach may not be able to do it?? But if he can, I'd say yes, do it. And yes, go for more timing advance.(mine has 5 degrees adv., 5% fuel curve increase, 255 speed limiter, 6500 rpm limiter, AC clutch lockout under WOT) These setting produced 9 rwhp/ 9 rwtq on my truck.
Best thing to do is call Leach, and get their recommendations for your application.

<< Well guys, especially Barret. How do you like your Mike Leach PCM's for the
4.7l? Should I go ahead and go get the custom flash. I figure I'd have the 5
degree advance (possibly more?), no speed limiter, raise rev limiter.
Anyguys change their computer and wish you could do more or less? Happy with
the performance increase you recieved out of the Mopar PCM?
Perf mods are: 4.10 gears, (30" tires though), Quick D intake, Magnaflow
dual exhaust. Soon to be are the Bruce Bridges TB when it comes out,
headers(?), MSD(?) and whatever else i can do for perf increase. Any ideas.
Thanks
