Ok, so I've got most of my issues solved for now, and my ka idles great, but I've got a severe lack of power. Compression is 163 on all four and I build boost well, but I've got even less power than when I was n/a. Just revving the engine there is a big hesitation after applying throttle. Plugs are dark sooty black, when i get into boost it gets plenty loud but doesnt go anywhere fast, no the clutch isnt slipping. Seems to still be running very rich. I have to have the distributor all the way clockwise to get to 20 degrees, which makes me think the lower chain may be off a tooth, but I'm not sure because it seems like it wouldn't start so easily or have good compression numbers. Running a t25 and enthalpy tune. Draw through z32 maf, and 370cc injectors, walbro 255 pump. Does this sound like a timing chain issue?
