I was just wondering what mods you could do before you should chip the truck, my first mods are going to be cold air and exhaust, later im going with a 4 pounder, just wondering. dont really want to void warrenty hell its already fast.

 

Some spring to mind:

electric fan
JDM heat exchanger
Ruslow underdrive pullies
electric water pump
headers/midpipes
weight reduction/redistribution
traction bars

But in my opinion, the engine is the last place to look for performance unless drag racing is your only gig. Much larger gains are available in the suspension and brake department.

 

That's what I thought too!

 

thought is right........just wait till you get some mods.

 

I dunno...I'm still 100% stock...

 

I have been running a 4#er for several months now without a chip and not a single problem...
