New Power Figure after Link G4+ Install???

Going for a Link G4+ PNP ECU in April

Curious to see what the new power figure will be, what do you reckon?

Current Performance Details
307.2BHP at the Wheels @ 5976RPM
353.3BHP at the Fly @ 5983RPM
342.3lbft of Torque @ 4426RPM
Peak of 0.88Bar of Boost @ 4855RPM

Nothing will change apart from Link ECU kit & sports cat installation & HKS FCON iS Piggyback w/loom, map & air sensor will be removed

Still on stock turbo/injectors
