Smart man but to tell u the truth the weak link on ur motor is the turbo size and waste gate.
You can tweak the ecu and frequency valve to its max value and you will gain power like what cobb and others claim. But if u ask me u need to set a target number. If you want 350hp find out which mod will get u there and keep inmind that u don't want 350 to be pushing every component to the limit. You need to have head room. Stock the turbo can do 18psi then taper to 12 psi it won't hold. Steady 18 due to the waste gate. Also fuel is an issue up top so u have to back down on the boost up top.
Ecu flash is fun but don't expect raw power! It will be strong mid range or accelerating but up top its going to run out of power.
If u want power go 1 turbo larger and more fuel then tune it. I would not bother with the stock.

slight bump like a nice meaty mid range pull... then just flash it... basically spike the boost to 18-20psi from 4K to around 6K then back it off to 12pis...
you will get a huge rush of power then taper down towards the top so you will get probably 20hp with 50lb/ft of torque...
you can do this with either open ecu or ecutek(which i think at this point is a waste of $$$)
so if you just want more kick but not a **** load of power just chip the sum beeotch.
i would like to do open ecu on mikes car with the crap he has in it now...
