Well, sure it won't hold 25psi out to 7,000rpm but it can hold a good amount. The power dip is likely cause by not understanding some of the torque management tables and therefor letting the power taper off up top like it is programmed to stock. You can request 100% max airload and all the Desired Air Load you want but you gotta play with some other places to get it to breathe happy up top.

Some of it is the turbo, and some of it is the tune.

I would ask for my money back with a powerband like that and wheel spin due to torque spike in that car.

200whp up top probably is less than stock, LOL. The problem with his crappy power band is that he's going to have a raging 1st gear, and then fall into a pile of manure in every other gear after that. So it's like you've got the worst of both worlds.
