Interesting differences were the JRM graphs show greater smoothing and the boost plot shows 1 bar @ 3850rpm, 1.5 @ 4600rpm and Surrey is 1bar @ 3200 1.5 @ 3500 Lamda/AFR is hard to compare as Surrey shows AFR whereas Sumo is Lamda however it looks similar - my AFR is around 11.2 at Surrey JRM showed the Lamda as around 0.7 (looking from 4 to 7k rpm).

Main comment I would have (and I have no data to back it up) was the car appeared to have been running much cooler at JRM there was no hint of it being really hot when coming off the rollers maybe I should have set up a data log however as my intake temp sensor still isn't working there wouldn't have been much point.

All in all a very professional setup and I would happily use their rollers again if they were closer!

I'll add the graph later.
Which is which ?
Would of been interesting to have seen the data logs of the dyno runs to have compared .
