M35 stagea boost issue

Hi all!

Im pretty new to the page. Buy i have come into a bit of a dilemma with my 02 m35 stagea and I'm hoping you guys can point me in the right direction.. sorry for the big parrlagraph lol

 

Now the other day i started experiencing when i put my fooy down not necessarily full through but if i boost to full bar its fine but after that its almost in a limp mode and doesn't wsnt to go full boost it loses power. The car sounds fine the spool sounds somewhat normal (just not going past full bar, almost like it limits itself) 

Im trying to explain it the best i can to give you guys the clearest picture.

When I shut the car off abd turb it on again its fine untill i hit close full or hit full boost at times its struggles to get there almost like a fuel cut/surge or like its missing. I don't get jolted into the winscreen or anythingbut its just there enough to notice it. Full lack of power almost like your  foot is 75% down on the peddle boost should be at about the same and climbing engine and exhaust sounds as it should but boost spool sort if stops mid way and power the same. Any ideas guys?

I had my AFM sebsor done  about 2 months ago so surly can't be that and I wouldn't expect it to be that with these symptoms. 

Car has an upgraded intercooler BOV and a car delete. Other then that its stock..

I have read somewhere that again it could be a number if things.. AFM, turbo seal or gasket leak, could be the turbo solinoid reading wrong, could be crank angle sensor or plain and simply cooler pipes or other boost lines being frail or have a split somewhere. 

If anyone has any ideas please let me know as most places where i live are typical mechanics and charge an arm n a leg to do checks and to get parts and theybarr hard ti trust..

Feel free to ask me an questions or if i can be any more specific to help resolve this would be really appreciated..

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
