JB4 and bigger turbos

[ThaShiznit]

Picked up some Stage 2 turbos to play with. Anyone use Jb4 to allow for bigger turbos? Been trying to get a custom re-tune from Heatsync but havent heard anything back from them yet. Seems like you should be able to allow for a higher psi with 3.5bar Tmaps and increase the injector duty cycle within the JB4. Or does anyone else know of a good remote tuner?

*Edit. N63 Engine and I have a custom Heatsync tune incoming. Will let them deal with the bigger turbos. They recommended that I stick with the stock turbos for now and then we can add them in later if we don't get the desired results.

TIA
