Both use UpRev chap. So if they both mapped it on the dyno, you'd get near as damnit the same result. What Abbey are planning to offer is a generic map(s) for members who have specific upgrades already made ready to go. So say you have plenum spacer, intake and exhaust, they can apply their generic map and its good to go. No need for the dyno work. Now in theory, it wont get you quite as much power as the proper dyno session (Abbey can advise), but may get you most of the way there, for hopefully, quite a bit less cost as you cut out a few hours on the dyno. You can always add to it and have a dyno session afterwards for a proper tune. I've been banging on about someone doing this for ages Revo do it for the VAG cars and offer various generic tunes based on what mods you have. The ECU should be able to tune (tweak) itself enough for the small variations between cars with the same mods
