Boost creep is a normal characteristic of the TVS style blowers. Mine is normally around 12.5 but goes up to 15.5 as I get to around 6k rpms. As for loosing boost between shifts, that is the bypass valve opening up when you lift your foot off the gas creating vacuum which opens the boost bypass valve. The only way to avoid that is to get the WOTBOX and use it's no lift shift feature which allows you to keep your foot on the floor and it just temporarily cuts ignition when you depress the clutch.

You could also just powershift the biatch but that's much more harsh on the transmission.

you're down on power, IMO. i have more mods then you but it sounds to me like you have the stock 3.75 pulley on the car, not the 3.5. 3.75 runs about 5psi and 400rw and with the 3.5 you should be around 8 and 450rw.

Since you did see a boost increase after swapping your belt (post dyno), having the other belt installed during the dyno could have resulted in your lower than expected results. But to Dyson's point, boost will drop between shifts due to the by-pass. Although mine is manual, I am right in line with Sinner's comments for a 3.5 inch pulley with 455RWHP.

just a FYI you might want to take the car back and get it retuned with the proper belt on the car for safety reasons. I'm sure if it was noticed that the incorrect belt was on the car while tuning, the tuner probably built in a bit of safety up top past where the car was hitting in the tune. But this doesn't mean it is the best tune for the car. You can damage an engine from having to much fuel or to little timing as well which is a way that tuners build in safety for boost spikes or if something isn't right on the dyno like the wrong belt which they know will get fixed once the customer leaves.

Now as was already stated having the wrong belt on the car is going to result in less boost and thus result in lower numbers on the dyno as well. Plus having an auto your numbers will be down a little bit compared to all the manual cars as well. so keep these things in mind.

im fairly new at this and yea i was asking breenspeed that, and they said they were supposedly tuning it for 9pounds of boost for the belt change, and they were mentioning something about a load. i was just confused and dazed on how they can dynotune something thats not in their face or on their laptop

 

[jusmillz]

and for the boost loss i really see it suffer on the 3rd to 4th shift it drop to five and just tried to go at a slug pace back up to 9
