Turbo lag with IA3+ ecu?

hi all,

just curious is this is normal.

I've been running Ian's intended acceleration stage 3+ reflashed ecu on my 200q20v for a while. the car is fast as heck, but i do notice some turbo lag.

i can't tell how much boost i have as the digital boost guage is dead (i have a vdo gauge i need to hook up).

from my experience - you start feeling the boost after 2,800 rpms or so - but you reall don't get pinned back until 4k rpms - it's pretty dramatic once you hit 4k. the car pulls like a mofo to redline.

stock wastegate spring and an 034 billet bypass.

is this normal behavior with the IA3+? when the car was stock - the boost was pretty seemless.
