last week I got the service soon light and had a code for maf sensor. nissan wanted to void my warrantee cuz of my gen 3's but after some arguing they replaced both. still have been having the random limp mode problem but other then that it was running perfect all the way home.
I have art pipes also so no cats
When you say code for MAF, do you mean out of range or high fuel trims? You might just need a tune.

This is something I dealt with before doing the major work, but I will continue to monitor and trace any leaks. At least it's not throwing P0507.

So far so good... engine is running smooth, and so far no warm start issues.
If it dials itself out, it could be lingering fuel trim that will eventually self correct (although I think you can clear those out with cipher). If intermittent, I'd try cleaning MAF sensors with that CRC spray.

If still no change, then there may be a small deformation or pinhole somewhere causing an occasional vac leak.

I actually had that problem on the OEM intakes! I over-tightened a hose clamp and managed to ever so lightly deform the plastic of the intake tube

If you still have any of those little L shaped resonator boxes in the intake to IM tract, I'd check those too.
