Not sure why you would need a 90mm MAF. No AUs came out with them, so I am guessing your EB MAF would suit. Highly unlikely you will max that one out, hence not needing a 90mm.

As for the tune, It is recommended to get the most out of the modifications that you have made. You have changed the air/fuel conditions of the car with the GT40Ps, cam and manifold. Without a tune, your ecu will provide the same fuel to the engine as it would have in the old configuration (EB), potentially causing it to run lean. Tune recommended.

Good luck
