Here we have the dyno charts from Valks coupe.

Before the ECU tune. 215 hp stock so there are losses of 45 hp through the drivetrain losses.



Valks chart after the dyno tune.
Let's say a gain of 18 hp. If we say we have a loss of 45 hp across the board then we have 233 hp at the crank.
I think the max hp I have seen on a chart here is 193 hp after the tune.
