Stav, when are you getting your bike on the Dyno at BSD? I%u2019ve got mine booked in for a dyno run next Wed as my low end fuelling is rubbish, ive got the Stage 3 Brentune flash so want them to evaluate it. Also will see if they can do 2 runs - as it currently is + I%u2019ll take the handheld with me to reset the ecu back to stock, if they%u2019ve got time for 2 runs, bearing in mind I%u2019ve got aftermarket headers on a Gen 1 so a very different set up to yours.
No idea when I'll manage to book a dyno run at BSD mate, I've been spending quite some time and money on my little Suzuki GSX-S750 at the moment so the XR has been dormant, mods wise...
It will be great to hear your experience and get BSD's feedback on their tune. I'm not familiar with Gen 1's but as far as I know the newer bikes run on wideband sensors and can be tuned to run almost exclusively in closed-loop mode targeting at set AFR.
