Default Bad maf?

Everytime I run the car a little hard afterwards for awhile when I out in nuetral it acts like it wants to die and drops to 500rpm Then back up to 800ish and does this a few times or untill I give it some gas. It does about the same thing like when the maf is dissconnected.

So is it maf
or tune for my mods?

Try changing your tps, I had similar issues in the past. The easiest way to see this is with a programmer or some kind of monitor that will show you your throttle percentage.

The throttle percentage looks normal. What should it be at around idle?

I cant remember right off hand, the problem I had was it would just start surging and you would see the percentage changing. If you want to clean your MAF just use some electronic contact cleaner and a qtip, it may help.

I'm going to take it for a test run and see if it'll do it again and I'll check the diablo

I cleaned the maf there was actually some nasty gunk but I took care of it. The maf reads 6g/s at idle And goes to 235ish at WOT.
is there anyone that can give me an explonation? Will the maf just startcutting out like that when going back to idle?
