Man those numbers are low geez I wonder why? I put down around 400-410@15psi a while back?? A dyno chart might help piece the puzzle together.Your mod list looks like it should produce some nice #'s.

Might have washed the bores and destroyed the rings....

Thats what I was thinking also because 2 of my plugs were washed clean with fuel. I will be doing a compression test next week after our socal picnic.

Is there any blowby, dipstick popping up?

No blow by

Tell me about it. I put down 307 on stock fuel, turbo with basic mods at only 13psi.

Compression test results are in:

1-130
2-145
3-130
4-145
5-140
6-145


I think I have a stuck open inj. as the #4 plug was cleaner than the others and smelled like fuel so that is probably part of the problem

I replaced all the plugs again and put a couple hundred miles on them and then pulled them out and it was only #4. The other one might have been from just too much fp as one was really bad and the other not as bad.
I have put in 3 new sets of plugs in under 500 miles so far to monitor them. They are cheap enough to just replace when I pull them.
