...which is exactly why I am looking to hold off until the Gen3 motors become available in the Tig.

I'd agree that if you are thinking of upgrading the turbo you should do this as a first step (saves paying for the tunes/work twice).

Though I'm still of the opinion that having a super car as a daily driver when most of the speed limits are 50/60/80 km/hr is a bit of a waste of time. Sure if you're going to run your car on the track it makes some sense but for a daily road car I'd probably still only go as far as a stage 2.
