OK update on the availability on the Mopar M1 intake, I just spoke with Dodge and they now have the M1 back in stock, Michigan has 35 in stock of each intake non egr and egr. This is great news as I was not sure they were going to make any more as this summer they were on back-order.
As DD94 and CW have posted the Mopar pcm takes to mods very well. Even if you get a cam that is called comp friendly the stock pcm will not be taking full advantage of that cam and the other mods. You're only other choice is B&G send your pcm out they program it and send it back to you, this must be done with every mod you make to the truck and gets costly fast.
I have had the Mopar performance pcm since day one and can't say enough about it, for our years of trucks it's the balls man. After 97 then its tuner time. 96 pcm's are half obd1 and half obd2 you have an OBD1 pcm that can't be tuned via a hand held tuner.
Yes it is even a big improvement over the stock pcm just by itself. I had the performance pcm long before I built my first motor for this truck and all I can say is best $485 I ever spent back then.
Do you have an EGR valve on your truck or not?

Edit: If you have plans to use 1.7 rr's this must be taken into account when picking your cam, going 1.7 will actually hurt your cam choices big time unless you go to bigger valve springs. What heads are you getting and valve springs?
You will or should be looking at getting a wide band 02 gauge so you can see what your fuel trim is at.
