I'm not sure if this will help you, but here is a HUGE tuning secret of mine for 2 bar tow tunes..
Run in P.E mode all the time except decel. This is easy to do with HPTuner; you just command p.e fuel at anything over 1% throttle. (Not 0%, this keep DFCO working), then zero out your p.e fueling, and add fuel solely from you b.e fueling. You will be basically running open loop, but B.E fueling will add at 100 kpa regardles. That way 2 psi of boost gets 13.5 a/f ratio (or what ever you want) at 2,000 rpm or 6,000 rpm. This makes tuning for fuel mileage and EGT much much easier.......
