50 trim stage 3 .60T .63E boost set to 20lbs did a data log with ms and it says that in a 3rd gear pull at 4000rpm 16.8lbs boost. At 5362rpm where i let off 19.6 , Does this seem slow?

Yeah, you should have full boost closer to 3000 rpm in 3rd gear if you floor it around 2300. Did you forget to put the valve seat in the wastegate before you bolted it on? Just checking if it's leaking out of the wastegate at idle will tell you if you aren't sure.

sitnger I have not messed with the wastegate since i put it on. This seems to have started rercently. I used to be able to nail it on a roll in 2nd and it would spool up and smoke em. And I can feel it is spooling slower. Could it be my tune, timing possible.

Should most likely be caused by an exhaust leak between head and turbo then...blown gasket, crack, etc.

looks like a leak at #3 on the top. Of course its a bolt thats super hard to get to. i was going to warm it up and try to tighten a little more but thats out of the ? Looks like time to change a gasket.

If it's been leaking for very long then the gasket is trashed. You'll have to replace it.

A standard felpro gasket is fine. If you want to have itground flat while it's off, you can install it with no gasket. Just put a little copper spray or high temp rtv on it.
