If I recall, the comp is rated at 180hp vs 120hp. Also, it starts fueling sooner, and fuels to 4000rpm.

125 horse is the comp as well as the drag however its a waste of time doin the upgrade if you have a HO motor. i believe its just harder fueling in the drag box.

The pm3 should get all the power that injector pump has to offer. What we call tst comp is actually a powermaxCE on tst's website.

I wanted the comp model because the fueling rpm range matches the smarty's. Now I have to see if I can ever get all the supporting mods together so I can actually use the higher rpms,...

From the FAQ on Tst's website:

The PM3 starts cutting back at 3000 RPM. The PMCE (Competition) starts cutting back at 4500 RPM.

The COMP fuels better down low...Resulting in more smoke and better takeoff!!!

Awall is talking about a TST brand chip, not an Edge brand!!! I would try the regular TST PM3 before you upgrade to a TST Comp. The TST Comp is a mean box to deal with and your truck probably won't enjoy it but it's a blast to play with...
