I am in need of some assistance. I have been trying to find a performance chip/programmer for my truck and I have had some troubles to say the least. I have an '03 1500 4X4 quad cab 4.7l AT. Every company seems to make a chip or programmer for the Hemi but nothing for the 4.7. Any suggestions? I'm not too knowledgeable in this area. My truck is a bit of a dog because the previous owner decided to put 355/50R20's on it. He recalibrated the speedo but forgot about changing the rings and pinions. So now I would just like a little more power without going crazy with the mods. A little extra fuel economy wouldn't hurt either. Thanks in advance.

Superchips does the 03 4.7.

 

The Superchips Flashpaq 3865 is available for your truck and gives a boost of about 20 HP/TQ.
And I'd agree, get them tires and wheels off and get you a nice set of 33/12.5/17s on it...

 

Welcome to DF.
I'll concur with the others, the Superchips is a nice unit.


One heck of a screen name u got there. Holy crap. Good thing for the "remember" box...lmao

 

Superchips.

 

Thank you all very much. I'm going to order a programmer now. Also any recommendations on tire brand HammerZ71? I do mostly road driving so I would like something that will wear well nicely.

 

Does anyone have any knowledge/experience with the new bullydog triple dog(40410)? ive got the sc 3865 but i was looking to swap it up a little bit. the one thing i like the most on the bd is that you can watch your current stats(ive got an 04). Any info would be greatly appreciated.

 

Haven't heard of any complaints with Nitto. I had BFG A/Ts on my F250 and loved them never came close to being stuck and the wear was good imo.

 

I have the new Bully dog 40410 and its awesome!! Good power increase as well as MPG.
