Default Tune review

Anything in this tune that would prevent me from being able to achieve commanded boost?

I have gone through testing ebcs and wastegate and both are functional, i did a boost leak test though the intake pre-maf. Details can be found in this thread.

I uploaded the tune and a 4th gear log, only thing that changed is i routed my catch can differently which i explain in the linked thread above.

If you aren't hitting boost targets, then you have some load targets in place that are getting referenced. Your WGDC decreases throughout the run.

Can't open your tune on this computer.

I thought that might be the case as well but I have gone over any load problems.

I linked to another thread where I was asking is my catch can could cause a boost leak, I did a leak down premaf and had sent air coming from the catch can.

I have a new one in order from jbr, I'll update after I install it Thurs or Friday.

Your ECU is trying to lower your boost. Catch can isn't going to fix that.

Post up screenshots of your Wastegate Duty Load Dynamics and Wastegate Duty Load Error Comp tables.

So I checked for leaks after changing the can, it doesn't leak from the can anymore but still not boosting over 20lb.

I'm at a loss and don't know what else to check hardware wise. I powered the ebcs and it clicked and air passed through the correct outlet.
I've done a compression test which was good, I've done a boost leak test, no leaks, I've pressed air into the wastegate actuator and heard and saw the lever move.

If it's the tune I'm just going to get a freaktune most likely, I just want to get everything good before that.
