If your ONLY concern is the HG/LR-Ping and have absolutely no concern about the High RPM Leanout and its accociated engine damage, then no, you do not need fuel mods, you just need to retard the timing to supress the HG/LR-Ping.
On both of my trucks I have chosen to fix both problems and that is what our URD kit is geared for, a TOTAL solution.

I installed the TMC 1.1 because I am most concerned with the pinging. I haven't had any fuel starvation problems (4,500 ft above sea level).
I am still planning on getting the URD kit, but its a little out of my price range right now. So the $100 TMC 1.1 was a better choice.

I wish you would of gotten the FTC instead of the TMC1.1. The TMC1.1 is a fixed retard based only on RPM. So it will retard timing even when you don't need it to. This can make it a little sluggish and affect fuel economy.
The FTC is fully programable and you can set the amount of retard based on manifold pressure and RPM, so it will only retard when you need it at a given boost pressure and RPM. This way it will not impact fuel economy.
You will also have the fuel controller installed for when you later upgrade the injectors and pump. It would of saved you money in the long run and have your truck running better now.
