I don’t think it’s any worse than standard though (or that’s what I’m noticing). Once the engine is warm it’s fine.

Potential gains from the 30D have been debated on the Forum many times, some believers and some nay-sayers, but leaving aside the ridiculously high output claims (mentioning no names) and having two independent dyno readings within 2bhp suggests to me that the numbers are real.

Ah, good to know. You must be over the moon with it! Enjoy, and thanks for the explanation.

I've had this fitted June 2020 by Soper with front break upgrade because mine did not have the msport breaks. I think it's well worth it and the breaks are a massive improvement and only raising the price of the kit by £300 or so. The car felt instantly quicker and no lag in the gear changes. Obviously an old shape now and many dealers wanted nothing to do with it.
