i have been looking at rpmoutlet.com at the package for the CAI, tuner, underdrive pulley, and throttle body spacer. First, would anyone recommend anything different for equivalent or lesser price and also would i need i custom tune with those addons? If so where could i get a custom tune with those mods? Thanks. Any advise is appreciated

 

Well first welcome to the forum its a great place! There are about 70,000 threads about tunes and there is a tech info center to read.
STAY VERY FAR AWAY from RPM OUTLET....very very far. No good can come from them.
There are not only better packages to buy but from far better tuners as well. They are much better and offer something that RPM will never Customer Service.
Do you own a V6 or GT? Either way try brenspeed.com and bamachips.com and also there is tuneableinductions.com (the one I recommend).
If you get a CAI you need a tune for most CAI, not for the UDP's thou.
Don't waste you money or time on a throttle body, its a waste.

make sure you read the tech section.

 

Justin at vmptuning.com has a very good deal on his 4.0 V-6 power package. I have one and it works great. Good price!

 

thanks a lot for the advice
