Hey Guys new to the forum just got my 2005 Chevy RCSB about a month ago Black LS 5.3 3.73's locking diff. 17" aluminum wheels. Have done a few mods Volant air intake w/ram air scoop tb spacer Flowmaster muscle truck cat back, 4 Yokohama AVS S/T 285/60R17 tires 2" drop shackles had all molding removed rear bumper painted black Gaylord's speedstuur wing lid windows blacked out and my worst mod (HPP3) currently on ebay for sale 299.95 BIN. Going to pick up the stuff for my TB bypass tommorow& getting a nelson tune next week any comments on my next mod (BEST BANG FOR THE BUCK) what do you guys think also has anyone tried a BBK throttle body or found a 160 thermostat for a 05 yet? Thanks for any comments or help.
Hey Guy to You

The Nelson tune will make a huge difference by itself!

First, nix the BBK, save your money. Maybe a mild port job on the stock TB if you're so inclined. The actual gains are debatable, but at least makes a cool sound, lol

Your std tranny w/ the LS is the 4L60E, so I'm in the "Traction Camp". For maybe $500-$1000, higher stall torque converter, shift kit and some other tranny upgrade bits and pieces. Fully build that baby for maybe another $500 in parts. Add traction bars like Caltracs. To get the full benefit of any other "power adding" project (LT headers and cam, forced induction, beefier heads, etc etc) you gotta get the useable power to the pavement.

E-fans are another nice mod. Although it doesn't "add" power, you get some back by losing the heavy old clutch fan. Since you got the 05' it might already have them.

You can find the 160* stat here at T Byrne:

Good luck.
