throttle body ls3
id like to thank a vendor (cajun4real) for taking care of me!! i ordered a ported and polished TB last week... i got it today... damn! the rough edges that interrupt air flow is so smooth.... instead of paying someone to do the job i did it.... even with getting the tools out it took less than 30 min... way too simple.ill post pics in awhile... if your on the bubble about doing it jump! its a cheap way to make your car run better... maybe cajun would jump in to explain exactly what a ported and polished TB will do for you.. thanks cajun (again)

I'm no expert, but re: question of what a ported throttle body does, info below on VMax PTB was in Vette mag a while back (dyno info is for LS3):
VMax throttle bodies are available for all LS-powered vehicles on an exchange basis. They're CNC-machined to smooth and straighten airflow past the throttle plate while avoiding the tip-in stumbles that plague some home-ported jobs. Installation is a simple procedure that doesn't require any tuning. Owners routinely report power increases of 8-10 rwhp and fuel-economy improvements of 1-1.5 mpg with no other changes. And since they use a stock unit as the basis for the VMax, it's totally stealth. That's a lot of value for $150. On a horsepower-per-dollar basis, the VMax throttle body is a clear winner. It performs flawlessly while improving power, improving fuel economy, and sharpening throttle response.
Dyno Results
stock throttle body, stock calibration: 363.80 rwhp/354.22 rwtq
VMax ported throttle body with stock tune: 377.83 rwhp/366.97 rwtq
