that TSI extreme kit isn't specifically for the QG18DE. The fitment will be poor and quality is even worse.

Gregor, if you're talking bhp, at 250whp you'd probably be on the ragged edge of blowing the stock motor. Using a lightweight flywheel on a turbo car isn't optimal because you loose the rotational momentum between shifts, causing a momentary lag of power as the motor catches up.
For 200+ wheel horsepower, on stock internals, I'd definitely use 2 step colder plugs. There are no reflashes.

I am talking that much power mike, i doubt ill be blowing the engine anytime soon though. Its all to do with tuning, you were using an safc werent you ? I'm using a replacement ECU (from microtech) that gives FAR greater control over what my engine is doing any point in the rev range, the only real comprimise is that my cold starts arent as smooth but ill put up with that for the safety of my engine. And ive got more power than other comparable set ups because of the tuning potential too.
Im failing to see why using a lightened flywheel would make a negative difference on a turbo car though.. On a small turbo you get through the rev range quicker and on a big turbo you will be able to spool up the turbo that little bit quicker getting you on boost sooner.
