I have been seeing on e bay that there is a manifold water bypass kit that claims to give 10-15 hp or somthing like that and an egr bypass plate that does the same numbers. Has anyone used or done this, and is a spacer block worth it on our throttle assembly and what can you gain, just looking for cheaper mods that work.

A almost free mod is the throttle body hot water bypass and there is no need to buy a kit. I used a piece of metal tubing (gas line) and two small hose clamps. Disconnect small coolant hoses from both sides of throttle body, install metal tubing to reconnect two hoses and tighten hose clamps. I also used rubber vaccum caps on the two hose connection tubes on the throttle body. You will lose a small amount of coolant so replinish your reservoir.

 

On EGR equipped engines the pipe that goes into the passenger side of the manifold from the EGR valve can be pulled out of the manifold and the protrusion that sticks into the manifold just to the rear of the throttle body can be cut off so it does not interfer with the air flow from the throttle body. I do not think you can remove the EGR valve on an EGR equipped engine without setting a code and the SES light.

Yep, what PDQrado said is correct.  The kit on e-bay includes items that you could get at any autoparts store for very little money.

 

People try selling crazy stuff on there.  I seen someone selling directions on how to get the "change engine oil" light to go out!

BTW, the parts you would need are a 1/4 inch hose coupler and a couple 1/4 inch rubber caps.

 

Here's a install on a Camaro, but the same basic install for the trucks.
