2 pulls 1st one i missed 3rd for a sec.

still have a walbro 190
ported manifold
and 3in turbo back on the way

what else do i need to do ? also i noticed that at about 2-5 # of boost in lower rpm range in all gears the car stutters but stab the gas anrd it pulls fine ?

Your first run looks terrible, you knock counts are dropping in and out at weird times. But your second run when the car was running hotter your knock counts are appearing were you would kind of expect them. If you can get rid the knock counts it will run much better. If you don't have anything to adjust your fuel trims you should buy something.

no nothing to adjust other than timing and a couple of other things im going to try tomorrow i shoudl have some other pulls tomorrow .

Do a third gear pull from like 3k rpms to redline and it would be much easier to read.
