Input from those who have SC their 370

[V8Killer]

Hey guys. I am not trying to start another useless thread so hopefully I get some good input from this. Currently I am overseas and I am already planning what to do with my Z but I am at a loss right now. At first I was going to go full bolt ons with a 100 wet shot. Just recently I changed my mind and decided to go F/I.

I want to hear from those who have S/C their Z. GTM/Stillen users. I will greatly appreciate your input on the pro's and con's.

My current Z only has drop in K&N air filters and a Stillen Underdrive Pulley

The modification that I am sure to add is a Boombop shop full catback exhaust.

I have to rework my list now that I am going to S/C it but I would like to know what parts have you replaced if any? i.e. injectors and fuel pump.
From what I read on the forum with the GTM setup you need to stay stock cats. Anybody proved that wrong?

My goal is to get at least 450 at the wheels. So please any and all input I will greatly appreciate it fellas.
