Thanks for the confirmation, okay so I went out, and I swapped out both MAF sensors for two spare ones, cleaned the hell out of the original MAP sensor with brake cleaner and cotton buds then electrical contact cleaner to flush it out and I also...

Correct the A is for the 2nd turbo but if there is a problem with the MAF'S there is a fault code. Without a fault code probably they work well.No A it has 3 wires and No B 4 wires.

Are there fault codes? Is it possible to accelerate in more than 2500rpm? Maybe there is not only one problem.

At the 1st photo is Mono turbo, up to 2800 rpm approximately. The 2nd photo is when the 2nd turbo works. What the problem is?

Hi. P006A-00 is a sign for manifold crash. Do a visual check initiall at the manifolds for oil and do a smoke test. If there is not crash at one of the manifolds, drive you car and check the RPM when you can't accelerate more and in what rpm's...
