Best stage 1 tune

Many stage 1 tunes have been discussed at length on this board, but it would be good if we could concentrate the comments in one thread.



The question is which tune, for an otherwise stock 235 (without bolt-ons), performs the best independently of costs, warranty issues or other considerations?



Ease of installation/removal is a practical aspect worth mentioning.



Please chime in from personal experience and, hopefully, some objective dyno runs.



The candidates are (feel free to add):



• AC Schnitzer

• Active Autowerke

• AFE Scorcher

• BMS Stage 1

• Dinan Stage 1

• ESS E-Tronic

• Hartage

• JB4 map1

• Manhart

• RaceChip Ultimate

• Remus
