Don't know that I'll ever stop learning about this truck I bought in February! New to Rams and Cummins.

It's a 2006 Mega Cab 2500 5.9. It has the tow tune on it currently (PPE Xcelerator Power Programmer).

Should I still be hitting the tow button on the gear shift for my heavy loads or did the programmer fix that too?

Just trying not to mess up the truck!

Also I am looking at possibly switching to the ARP head studs.

Will my truck then be ok if I play around with the other two (performance and extreme) tunes on the programmer?

Not trying to break something.

Thanks!
