Except that it hangs right at 13AFR with a more restrictive intake, analog of which you could get if your oem filter gets dirty.
Another thing - I see that at least one of those tunes makes the car significantly more sluggish in the DD driving than OEM tune, that is under 4k rpm.
Thanks for info OP, I'm staying far away from these, not worth bothering.
