So does the car feel slow? If anything your gauge MAY be off. Or you have a leak somewhere.

I know someone who threw a 02-03 TD04 into a 04-05 and it didn't boost properly due to the settings of the wastegate.

What other mods are you running?

Oh ok! Nope no CEL at all. She runs fine and the torque seems normal but it just feels like she can boost more ..

You should be hitting more than that though. I don't use sport comp. So I'm no help there.

Hey Guys so just an update to my issue here.. I finally found out what i needed to do to regain my stock psi back to 12. I needed to replace the actuator from the 2.5L to my original 2.0L and that fixed my boost issue! Thanks again for the help and suggestions guys!

I'm curious why you didn't do this when I told you to earlier?

Move your wastegate actuator from your original turbo, unless there's something wrong with it.
Also "setting" the actuator was not to do exactly 6 half turns. That video was for a different turbo. You needed to continue to go tighter until you reached proper boost. Start at 6 half turns, and then go 7, 8, 9, etc... until boost is correct. This would have had the same effect as swapping the actuator.
