A few possibilities I can think of:

1) You don't have the latest tune improvements that Jessee and I have been testing. We received the updates as custom tunes. I don't know if the improvements have been pushed out to the official Prodigy tune on Diablosport's servers yet. The latest tune has big improvements in the lower RPM area.

2) I have found that the turbo does not respond well to sudden full throttle, especially at low rpms. The engine seems to bog down a bit with sudden full throttle. From low rpms, instead of stomping on the throttle, try a smooth transition to full throttle. You can still quickly transition to full throttle, but just don't suddenly stomp on it. At higher rpms (4000+), it will respond more quickly to sudden full throttle, but smooth throttle transitions will always give you the best results because it allows for the turbo to keep up with your demands. I believe this is just a normal characteristic of a relatively large turbo. It doesn't bother me, because I prefer smooth acceleration transitions anyway (your drivetrain probably prefers acceleration transitions as well).

3) The turbo can't really produce a lot of boost until somewhere above 2500 rpm. 1st gear accelerates quite well below 2500 rpm, but if you are in a higher gear, then you'll always get the best results from downshifting to get rpms above 2500 rpm if you really want to accelerate. That's one way the automatic transmission would be better. If you use a lot of throttle with the auto transmission, it will downshift. The manual transmission gives us the opportunity to be lazy and wish we could just accelerate quickly from lower rpms

I think I need a more detailed explanation of this to understand it. Are you talking about driving steadily in 3rd gear at 4500 rpm, then stomping on the throttle? If so, then there will be an initial lack of power as the turbo spools up. This is boost lag.

Now we've got 3 people making about 8.0-8.2 psi boost. Jessee increasingly appears to be the outlier with 9 psi boost! This really makes me want to crank the boost up to 9 psi with a manual boost controller to experience some extra fun
