I've got the RodPod installed on my 2002 - love it and I think it's the only way to go. I've got to open it back open since the light on the EGT isn't working (loose wire connection). I did a post of the whole install process of EGT, Boost and Fuel Pressure. Do a search by my user name and you'll find it.
My main reason for going with the RodPod was the Pillar just looked big enough as it is and I didn't want to add more stuff to it.
Besides, you can get a 4th gauge in it if needed!
