Hey I recently bought my first Dodge. Its a 03 1500 qc 2x4 with the 4.7l. I have already lowered the truck 2/4, k&n cold air kit, throttle body spacer, superchips tuner, jba headers with magnaflo exhaust. I still want more power out of the truck though. I have a 10p shot wet kit on the way. I don't know the best ways to get track performance out of these trucks as I ha e never owned a Dodge. Please help with some pointers thanks.
And they guy I bought the truck from said he put a set of custom grind comp cams. I can't hear anything so not sure if that's true. He told me the computer is advancing the timing to where u can't hear. Never heard of that either.

 

First things first: You own a 4x2, a 2x4 is a piece of wood.

Secondly: You have a fuel rail - gas is not injected directly into the throttle body, so remove the paperweight you call a throttle body spacer, it's actually costing you a bit of performance.

Aside from that, it looks like you have the basic bolt ons/tuner deal covered. So the next progressions would be ported throttle body, polished heads and cams...

 

Since you have a 4x2, gears. 4.56's will help that 5000lb beast with the baby engine get moving. Was the Y pipe replaced with the headers? There's a restriction right there if not. Other than the 08+ intake manifold, I don't think there is much more you can do before forced induction. Go to airram.com and shop around.

 

^ Yeah, what he said too...

 

They are heavy trucks to get moving in a hurry (mine's over 5500# on the scales). The gearing has made a huge difference in terms of get up and go with the hemi so I can only imagine that the 4.7 would benefit even more.

 

Well sorry. 4x2. But thanks guys. It is a heavy truck and the gears would help. I don't know why I didn't put them in when I put in the locker. Ill have to take the spacer off and see how it does, but that does make sense for it to not help. I looked at airram.com and I'm thinking about ordering one of there intakes.
What do you think about 206 or 212 cams?

 

And the shop left the y pipe instead of running true duels. Ill have to get that changed.

 

I have heard the best cams for the truck 4.7 are the HO cams, but good luck finding them. You will definitely need custom tuning if you put either Crane cam set in.

 

Yea there are a couple dyno spots here. I'm sure somebody can do it

 

I ALMOST had a set of HO cams for sale, but I decided to rebuild my 4.7 HO when it dropped a valve seat, sorry, LOL.

The 212s are nice, a buddy of mine had KRC Performance do a set on his Dak when Marty was still at KRC. Gains are better'n the HOs, the big reason the HOs are in such demend is you don't need custom tuning...
