Your butt dyno really really needs some tuning, in fact I would go out on a limb and say you need to upgrade to a new butt dyno, one with buttons instead of a zipper one that is relaxed fit vs flared bottoms, one that does not have a patch of the american eagle on the back right pocket.

APR as seen on the timeslip is not the weakest chip on race gas, race program can adapt and it runs darn well.

And on my car, all chips boost about the same 1.1 1.3 (spikes) of boost, while the XR is rumored to almost hit and or hit that magic 1.5 bar number in higher gear low rpm scenarios, but I don't race in those conditions. I have not driven the MTM, but I really want to try the MTM stg III chip.

AMS is in no stretch of the imagination as fast as the XR, there is nothing currently that can touch the XR. It's currently the Desert Eagle of stage II chips.
