Whats wrong with this picture/compression?

[SpoolingSpyder]

Did a compression this morning because my car has no power under boost ( from right to left 150, 150, 135, 145).. It boosts fine. But when I go WOT the car sounds like its flooding with AIR or FUEL and not responding to boost. I just put in a SAFC2 and have evrything set to 0( so I think). I found out I have a bad front o2 sensor but doubt thats the prob. Anyone ever experianced this or have any clue on what I can do next?

Well, compression on #3 is a little low compared to the other cylinders, but it seems you're JUST within spec......

Have you checked your car for boost leaks? This is probably the #1 cause of lost power under boost in the DSM world.

Do you have stock injectors? It wouldn't be o2 sensor because they really don't do anything under WOT.

sounds like you need to log your car to see what's really going on.. if you have too much fuel or air or whatever the case might be and adjust it accordingly with the safc.

Yes I have stock injectors with 135,000 miles on them. I have a ported 14b all bolt ons, 255 walbro, intake, HUGE FMIC, manual boost controller etc. I have the car running 10 lbs atm, used to run 20 lbs like a raped ape! Now all I get is lots of damn air/fuel when WOT! I will redo all innercooler cuffs and check for leaks the best I can. Gunna get that O2 replaced along with injectors/electronic boost controller, egt gauge etc and try and tune the best I can. All I can think of is too much air or fuel or boost leak or crap injectors. Thanks for all your replies as I could use afew more hints on what I should look over.

I don't see a fuel pressure regulator to accommodate that 255lph fuel pump, that could pose a problem.

Hey, 20psi on the 14b, with stock injectors, good or bad?
