Hey everyone, I'm newly registered here and would love some input in an upcoming rebuild/improvement opportunity I have soon approaching in my Suburban. I am currently in Afghanistan so it will have to wait a few months until I get home for vacation.

I have been in discussion over at GMI in the performance section (link) and have come down to a list of what I can do to Betsy (my Suburban's named Betsy).

First here is a list of what is already done to her:

2001 Suburban LS 4X4 (yeah, I lowered a 4X4)

Suspension
-3/5 drop on 22" Panther Vector's MB512's wrapped in 305/40R22's.
-Poly-whatever-it's-called sway bar bushings.

Engine (LM7)
-Throttle Body Bore (Wow what a difference this makes!)
-Throttle Body Coolant By-pass
-EGR Valve Pipe Mod'd (cut)
-MagnaFlow Muffler: single 3-1/2" in dual 2-1/4" out through Dual 4"tips coming straight out the back
-Dual 16" Cooling fans on a stand alone controller. (3mpg highway increase )
-Cheap CAI system off ebay
-Mail order tuned

Trans (4L60e)
-Mail order tuned.

Exterior
-New all chrome grill (plastic)

Stereo
-Kenwood Pop-out touch screen DVD/Nav head unit
-4 Kicker 6" Components with 1" Tweets and crossovers
-2 Kicker 12" L5's in custom enclosure
-4 Channel Memphis Amp 100W RMS per channel @4 ohms (running 2 ohms right now)
-Mono Memphis Sub Amp 1000W RMS @4 ohms (running 1 ohm right now)
-Kinetik Battery (capacitor replacement = something like 700 Farad)
