Thanks Giallorosso. i got the flash done early Saturday morning
The power is great, but it just seems to surge all of a sudden every now and then. i was told i will need a few hundred km's before it settles down. the turbo lag is still there and i really hope it smoothe's out soon. thought it may have had something to do with the traction control so but it is the same on or off.

Have you upgraded your diverter valve as well? The stock valve just can't handle the extra pressure and will leak causing the surging you describe.

Surging from a chip does not sound right, but I don't know the Giac product.
The poor airflow from standard intake can cause some issues and varied response when putting your foot down.
I had some fluctuations in boost before doing the dump pipe and FMIC mods. There is also the N75J valve and N249 bypass which address surge / boost fluctuation issues. You may want to have a look on Polos.net (http://www.tigerstyle.co.uk/phpBB3/viewforum.php?f=43) for some info on these mods.
Sending a thanks to Blitzen for the good price on BOV and for installing it for me this evening.
power delivery seems much smoother now. i think it was leaking a lot of boost. Feeling much better about the tune now.
the only thing i do notice is that the car really hastily jolts if i go from say 75% to 50% throttle once the turbo is spooled (but i assume thats the bypass valve kicking in somewhat)
