I was lucky enough to figure out that my car does not have rod knock before I tore it down.

I did a search to see what the fuel damper did and got mixed results. So when I replaced the original cracked rubber lines on my car I deleted the damper. The short piece of rubber hose between the damper and the rail was a little tricky to make, so I decided it was a good time to leave it off. About the same time I started hearing a slight 'tap tap tap' sound at idle. Last week I installed a Bosch 044 pump and big injectors and turned up the boost. The 'tap tap tap' got louder. I was really worried. I just happened to feel the rubber fuel feed line while the engine was running and felt a sharp pulsation in time with the sound. Then I figured it out. Since the injectors all fire at the same time they send a sharp pulse through the rail and feed line, similar to the water hammer effect

So the fuel damper is going back on tomorrow.

What else should I know? There's plenty of good info on the forums, but I'm sure there's some obscure tidbits that are rarely mentioned, right?

What else should you know?

best think to know is... when something goes wrong, look at the last thing you did to the car

xsboost90

all the injectors fire at the same time?

Rogue_Ant

Yes, if you are using the DME...

Its called batch fire. I stopped mine from doing that.
