my eforce performance questions

i have auto 09 gt with zero mods other than my eforce with an competition cai upgrade on it with a 3.5 pulley . i took it to breenspeed to get tuned and dynoe'd with 5 pounds of boost on it(due to wrong belt being on, with belt slippage) , it made 395 to the wheels on a 87degree day.........im just wondering whats your guys number and should i have made more or not.
got home and changed the belt its now making 9pounds of boost.
Another question ...often it has a very bad wide open throttle lag, for instance i floor it and the boost goes to five then waits (lag) and shoots to about 9 psi, it only does this sometime, i wondering is it something in the tune or is it just the characteristics of the eforce.

another question......it also loses boost in between shifts , lets say its at 9 and shifts then drops to 6psi and tries to shoot back up for 9psi, is this normal?

need answers,opinions,ideas,or suggestions....thanks

My procharged stang made 495 at 10 psi. It will bleed off boost during shifts to keep from damaging the motor so it's normal for it to drop.
