Boost Struggles To Go Past 2psi

Start taking pipes off from your throttle body back - when you start getting 0 (zero) boost when free revving , then you have found a blockage. Check each pipe section as you go. That is - if you have a blockage.

If it was working OK before - try to retrace what changed between then and now.

Good luck

I only have the stock boost gauge.

Kind of understanding where your coming from.

I am going to try and figure out whats going on.

Just have to figure out where to start.

If you didn't have the problem with the standard cooler and have the problem with the aftermarket one it stands to reason that the problem is with the cooler or piping. Pull it apart and check it out. sounds like you have a huge leak or a huge restriction.

Hi guys,

Got stuck into it yesterday arvo.

Took all the pipes connected from the throttle body up to the afm.

No blockages. But I did however put the stock T piece boost controller back and once you rev it on idle the wastegate doesn't open up anymore.

But I am still where I stood from the beginning, boost wont go past 2psi.

      Unpeeling the Orange

      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.
