Ok guys, help me out here because I'm not familiar enough with the new 600's so I'm asking the experts. If you read me other thread you would have seen me ask about the Dr. P chip for my friend.
Well he bought the stage 1 box and said that he is not impressed.
I have to take his word for it as he's in AZ and I'm in CA. He's getting beat by a D-max while towing, and we all know that we can't have that.
So what he wants to do is build a nice tow rig with power... and he needs it down by the 22nd of this month. I told him the obvious things to do but PLEASE correct me if I'm wrong. Change the air filter to an AFE, since it's a AZ truck I'm pretty sure he already has 4" exhaust all the way out
so I guess the best thing he could do in that department would be to change the muffler?
He was thinking about doing propane but I know the Cummins aren't to happy with that? But he would only use it for towing. Like I said I need help here.
So what I'm asking is what's going to be the best way to build this thing? Chip, intake, exhaust, injectors?
P. S. The trucks a 4x4 Auto, with 3. 73's.
