Understandable, which is why I took the fact that I have an xi into account in my review. I was expecting more than "hardly noticeable" gains.

I don't have a boat anchor, neither does it justify the fact that this tune is any good on an xi.

Too bad the tune is "minute". I really need to roll in a tuned N52 to make an informed decision and jump from over a PBX.

Do they alter the valvetronic in stage 2?
Thank you, I appreciate it!

I think people mostly do these tunes for the throttle remap, which is what you're given with the PBX. 10-15 hp is minute, after all. AA has always stated that this tune alters the valvetronic.

I was under this same impression.

I thought the N51 was a "detuned" N52 with three stage intake manifold.
