Not building boost, no CEL's

[bluelights81]

Hello everyone. I have a 2000 Accord, with a built F23, which has a P28 with Hondata S300 installed. I am not a tuner, but after a few years of the car being down due to a cracked cylinder wall, I have recently got it running again with a new built block. The car was previously tuned and it runs fine now, but is not making boost. I have checked all the lines, charge piping, etc. and also checked my previously installed boost controller and everything appears to be normal. Once getting it running again only a few weeks ago, I was getting a P0335 code (crankshaft position sensor circuit fault) which was throwing the car into limp mode, as the RPM's would cut off at 3500. After replacing the sensor to no avail, and after extensive research I found the problem to be a KSTuned balance shaft delete kit which I used the supplied aluminum spacer in place of the balance shaft pulley. I removed the spacer today and installed a stock pulley and the CEL is gone and the car is no longer in limp mode. It's not however making any boost. At idle, according to my AEM boost gauge, it's pulling 22-24 lbs of vacuum, however as soon as there's a load it stops at 0 and does not build boost. My question is, does anyone think this is a software issue with Hondata? Or does one think it's a mechanical issue that I could resolve? Possibly seeing as the CEL kicked the ECU into limp mode, would that affect the tune and software settings? Again I'm not familiar with the software personally, just looking for some direction. I have an appt with my tuner here in NH shortly to get a fresh and updated tune, just trying to get it to at least get the turbo building boost before I drop it off as it's one less thing he'll have to address. Any advice would be helpful.

This could be any number of things. Is the turbo spinning?

[bluelights81]

Yes it is spinning freely, and even faster when I rev the engine manually at the throttle body.

Is the waste gate open or closed?

[bluelights81]

I pulled it off the other night and it's shut, when the car was off. There is what appears to be a small sliver of daylight when it's fully closed though, not sure it that's normal or not, like paper thing but I can see a small gap. Not sure how to tell if it's open or closed while the car's running.

You need to see if it is open when trying to make boost.

If it's an external wastegate just remove the dump return pipe temporarily and drive it around, you should be able to hear if the wastegate is opening or not.

If it's internal you can move the shaft and see if you hear the flap open and close. I've seen those shafts bent from everything resting on it when it's out of the car
