Any other standard cars run today?

Stock cars won't make 18bhp over what they should be making so I'd personally question the RR or operator.
Even a Green filter won't give anymore than 1-2bhp.

as normal yeah
Yours isn't the 180 bhp model and it's actually reading low due to the hot conditions, is it ?

My standard 150 bhp AGU (apart from a full milltek) ran 148 at JBS (Mid April.. coolish conditions) and 163 at surrey rr, (Late March, fairly hot) JBS is supposedly deadly accurate and other cars, Wilko/R1GTI, were running down, I think because of the heat, (at the surrey RR day). James (@ JBS) said the full milltek is not holding enough pressure so your turbo can't supply enough boost to give the power, of course, a remap is what's needed. The surrey rr.. who knows ! probably a different setup on different days on different rolling roads. I reckon it's probably somewhere between 163 and 148.. so 155 ish.

Might be a good idea to go back after getting it checked over and ask them to run the same settings.. nowt like another run for comparison, I guess ?!?!

"catchphrase time"

Dyno Lottery. Just compare yours with others on the day, as 'relative' power figures.. choose a datum and reference from that.. its as close as you're going to get on a chassis dyno.

JBS's rollers do read stock power levels on stock cars, so is a reasonable guage I guess. Some others rear higher than stock, and you hear VAG engines (1.8T) produce more than quoted usually as a reason. Maybe they do.. but relative to them you have a comparitive figure again.

Your plot looks reasonable tho.
