1JZ ignition problems

Ok, my 1JZGTE seems to be having a couple of problems.
First of all the mods,
600x300x90 Bar and Plate cooler
2.5 and 3" SS Mandrel IC Piping
2.5" Dual Dumps straight off the turbos.
K&N Pod Filter
There is no boost control used.
Now at around 0.9bar - 1bar I am having the ignition breakdown and misfiring. I have hit 1.1bar and hit the boost cut so I know it's not that.
I have changed from the platiums to coppers with 8mm gap, no change.
I have changed the coils for 2JZ ones (same) and made no difference.
I have changed the igniter for a 2JZ one (same) and made no difference.
We did notice that the Map sensor was plugged into the wrong port on the plenum so we fixed that and plugged it into the filtered one. It fixed the problem for about a day but now it is back. Could a dodgy map sensor cause this?
The car seems to overboost though so I thinking that is a stuck wastegate and/or leaking wastegate line also.
