Re: Need Help! Simple mods how-to's and how-not's The PCV mod addresses oil consumption and will yield no performance gain at all. It is designed to cut down on the amount of oil that gets into the intake manifold as a result of the engine simply running.
The TB bypass mod is designed in theory to help get power up by keeping the TB as cool as possible to eliminate the minimal losses experienced by the hot coolant raising the intake air temperature. I didn't catch where you live, but if it is someplace that gets cold weather, leave it be. If you are hell bent to do it, you can but please dont expect the gains to be measureable at all in most cases.
The website www.ls1howto.com has a lot of great write-ups on a lot of mods. Basically, you need to pull the black coolant lines off the TB, use a piece of metal tubing and clamps to essentially join the two sides of the hose and use rubber plugs to seal the TB holes. It's a very easy mod...maybe 20-30 minutes if you slack off. Kits are availble, too, from the sponsors!

Re: Need Help! Simple mods how-to's and how-not's Neither is worth the time or effort IMO. The by-pass can be convenient if your TB comes off a lot but otherwise not necessary unless you go hardcore with your motor. If it snows were you live don't do it.

I don't think the TB Bypass mod is worth it. You'll see zero gain from it. There's no point IMO.

1. Less chance of false knock.
2. In some instances can help alleviate what is commonly referred to as piston slap.
3. Keeps combustion chambers from building up oil residue, which can also cause your spark plugs to foul quicker.
Some mods have benefits other than RWHP gains that can still make them worthwhile.
