Yes, could be that Stage 1 of about 290 HP and 370 TQ (per their website) is OK on 95 RON / 91 AKI, but that TQ figure seems like a massive gain and makes me nervous - must feel amazing though.
That TQ is the same as the stock M340i! I am sure it must 'feel' a lot different being delivered by a 3.0 litre and 6 cylinder vs. 2.0 litre and 4 cylinder though.
Anyone seen any posted drag slips from a 330i with Stage 1 running 91 AKI octane?
