I have an update on one of those tips!

If you look at that article, I went through with number three which is taking out the Head Shim. I did this, and soon after I finished, I ran my HPI RS4 3. OMG! This was sweet. The car was hyper compared to before. It added a Sh*t load of power and acceleration, not to mention the at-least 8-10mph of top speed added. It was the added compression that did it. I almost pissed in my pants when I tried it out. I could not be any happier with the added performance. I will soon do number ten, which suggests to open up your headers.

It was pretty simple overall. If you do choose to do what I did, be sure to be VERY careful though. Because, like they said, it might not work with all engines, and if it is run that way on an engine that cannot allow it, it may cause damage. Also, be VERY careful not to strip any screws holding your head on!

Just letting you know,
