Looks very healthy for only 1.15bar.
How is the 'engine horsepower' calculated? Do you have wheel horsepower #s?
Wheelpower was 111.9HP /215Nm
The guy did 3 runs to get the losses and rpm right (got no revcounter yet). The bench should be ok because a few cars later was a dude who went on another bench a few weeks ago and he ran 7HP more that on the other bench (he changed his exhaust to large diameter freeflow)
