The Dyno Graph with the 25,1 Hp is with a C21. With the Proto of Pro Flow Gt Exhaust the Score is higher... but we had a Data Crash and current no other Dyno Graphs.
In 2010 we will start testing the R/T Cylinders, and make new Engines.
But you must remember he is so popular in Germany, almost everyone wants to talk with him on ICQ because of the developments and other additional matters
Hey,
It is very hard to reach Pro Flow [Adri]. Maybe you can write him a PM on scootertuning.de ? His nickname is Nudelfritz.
I have Stage6 R/T 70cc and MHR TEAM II tuned by PF and they both look really great but I can't say how powerfull they are, yet. We can't also say if PF tuning is the most powerfull tuning in Germany, because there are also other great tuners like MRZ[Kochi] and Kiesler Someone would have to test on dynobench cylinders tuned by those guys on one setup and post here the results.
If you are looking for a good tuning I can really advice you PF tuning
Greets,
Bartek
