It was interesting, the tuner is not a real fan of the FA20, but he did confirm that compared to many inline fours it does quite well in terms of torque... thankfully I guess, with a relatively low rev ceiling HP is always going to be more of a challenge.
But then he taught me a lesson in humility when he overlaid some Nissan GTR dyno runs he did the day before, with some light mods (nothing internal) and a still fairly conservative tune...over 1000 Nm at under 3k rpm...and docile enough for your mum to drive to the shops.
