Won't boost past 10psi

Won't boost past 10psi

Hi, r32 gtr, boost restrictor removed and still won't boost past 10psi. It's got a mines ecu would that make a difference?

how do I work out what's wrong? I want 15psi and I thought removing the restrictor does that

Has it got the stock solenoid? Sure the Mines ecu is the only change? Lose the Mines ECU and get at least a Nistune chip instead.

If you want to live on the edge...... disconnect the actuators and CAREFULLY drive the car to see if it will get over 10psi. If it does then there is an issue with the boost control side

autometer boost gauge plumbed into the line going to the map sensor.

 

still haven't tested driving without the wastegates connected as im unsure how to set that up. do I just remove the vacuum line to the actuator and just block it so I have the turbos there without any vacuum hoses going to it?

 

car originally had a boost tap installed where the stock solenoid goes, I removed that and put the solenoid back in expecting to have a bar of boost.

Yes just disconnect the actuators and block the lines that were going to them. Also be careful not to overboost

Just unplug and block the 2 lines from the solenoid and see if it spikes above 10psi. If not remove the rag from the intake blocking the intercooler.... like mine was haha

      Misfire issue
      Hi guys wondering if anyone can lead me in the right direction.
      Car is misfiring once hits 10psi, whether it be in low or high boost it misfires from this point.
      It is a r33 with built rb25det running 310rkw on high boost.
      Car runs up to 25psi.
       
      Changed plugs like for like BCPR7ES and continued with the 0.80mm gap.
      The split Fire coilpacks were quite hard to get off but now they seem to go on super easy and off quite easily too once 2 bolts removed of course.
       
      Any ideas as I am stumped? 
      Cheers
