It's for my mate. I put a post up a few weeks ago about a place wiping his map off his ecu so it was run on his rollers today to see what base he had to start off with. It's a bit low even with the standard map considering its got a few decent mods.

Yeah most of the time it will be around 15 or 16% loss.
Not always though.

240 x 1.15 = 276
250 x 1.15 = 289

15% loss is a half decent rule of thumb for a FWD car

That's not how you calculate back percentages.
240 is 282 and 250 is 294

A dyno calculates losses on coast down, generally, so adding 15% at the end is more accurate than your way.

Standard Cupra r is 225bhp, closer to my original 'wrong' estimate for a standard car...
