This is another set of noob question .
So here goes
I have a 2014 2500 that just got the full "D"
With S&B CAI and 5in turbo back
I'm running the csp4 tune EFI live by Ryan
My question is do I buy the csp4 switch or the csp5 switch?
Or do I just switch to the tune of my choice with the auto cal?
And if I buy the Csp5 switch, does it come with a new tune file?
