New td05H with hesitating and surging issues

[insanity007]

I've just put in a td05h with a chip to run it up to 16psi. I was running a different chip up to 17psi no worries on my Td04 before.

Now I have hesitating issues with car around 12psi when it suddenly surges up to about 19psi and drops back to 16psi. I've had new coils fitted and the spark plugs gapped by Subaru & Misubishi Evo Performance Specailists in East Tamaki. They ran a fuel test on it and said there were no issues with leaning out and the guy there said it was running a little rich but nothing to be worried about. The sparks are also platinums and only 2 months old.

They also fitted my GFB BOV for me.

It's especially bad in 1st gear and gets less noticable through the gears.

The pod filter is new and isn't really obstructed by anything.

I've got a green sticker AFM.

Oh and it's gone into a v2 GF8 and it's a 16g TD05H

How?

If it didnt have the issue before with the old chip, sounds like a dodgey chip. The airflow meter should allow the engine to see the correct airflow to enrich the fuel mixtures, so there should have been no need to replace chip for a different turbo? Sounds like the new chip has poor boost control. Try the old chip and see what happens
