Just had a BGB/RMW tune done on my R and am one of the members who was very skeptical.

Since I wanted to make sure of what I was getting and adjust if needed with custom, paid the extra for custom/dyno results at a dyno I was familiar with and I am now a believer in BGB/RMW

Personal experience with this Dynapack dyno (have used it many times) is that on a Cayman it reads about 15 hhp (hub horsepower) below crank

My '10 S baselined at 317 hhp and my R baselined at 317 hhp (there's that Porsche marketing again) After testing other Porsches, it was figured that the S was underrated and the R was closer to actual.

The 329 hhp baseline of my R on this is with a Remus and Vflow, which were 7 hhp and 5 hhp over stock respectively.

 

Very interesting. Is the 15 hhp difference only at peak and non-linear or throughout the power band?

 

The gains are fairly consistent across the rev range.
