Did a compression test and........

Here's the whole story

Today i did some pulls with another ARP chipped A4 (Sergeo Silva...V@S shifters).I have an Apr chip with an exhaust and K@N. We are both 99.5 and i have bout 62000 miles, he has more. He would pull 2-3 car lenghts on me pretty good in the lower rpm and slightly in the top end. We couldnt belive it. This was the case in any gear. Needless to say i was pissed.

With in an hour i did a compression test and this is what i found. 1st cyl. 168 psi, 2nd 167, 3rd 160, Fourth 155 PSI,

I was planning on going stg3 this spring.
Am i screwed?????

I would like the opinion from some of the more experience members.

... I run a solid 15.4 in the 1/4 and burn no oil or coolent.I'm also not leaking boost.

k thanks

I think you should be running 168 across the board..

In the cylinders with the lower compression put a little bit of oil and test them again. If the compression comes up it may be time for some rings.

Re: Did a compression test and........

Let's put this into perspective. All four cyls are within ~10% of eachother. I find it odd that the compression goes down for each succeeding cylinder and suspect some problem with the test rather than the actual cylinder compression.
