[s-cars] Whats the best chipset for a full RS2 setup

I have the RS2 setup (minus the cams) and have tried 3 different
chipsets; B Pastore 370 (aka S Eiche), Lehmann and Dahlback. All of my
testing is with 94 octane.
The BP 370 pulled like hell, lots of power, but pinged too much for my
liking - only the addition of toluene made the pinging go away. Boost
was 28-29 PSI.
The Lehmann was a dog compared to the BP 370, very lazy below 4000 rpm
and the hit was not there, kind of a smooth acceleration, almost stock
like. The timing maps were not very aggressive, IMO. Boost was less,
around 24 PSI.
The Dahlback is a good compromise, very similar to the BP 370, perhaps a
little less aggressive and the pinging is virtually gone, however it
does ping slightly on occasion. Boost is 24-25 PSI.
If you are running a stock intercooler, then I'd recommend the Dahlback,
if you have a FMIC or water injection, then I'd say go with the BP 370
to take advantage of the timing maps.
The other option is MRC Tuning, sold by Bob Meyer, perhaps others can
provide opinions on their chipset.
You shouldn't need an adjustable FPR, the OEM 4.0 bar is just fine.
