Thai d40 full throttle engine shutdown

Hi all here’s a problem I can’t figure out
Have a 2010 Thai built d40 2.5 auto running a tillix valve setup as got sick of replacing genuine Nissan parts that kept dying so when you hit anything over 3/4 throttle and have any load on engine the vehicle literally shuts down you lift your foot off the accelerator and it will come back to life does it on cruise control also have checked vacuume lines and replaced them all had new exhaust manifold and gaskets fitted to turbo any ideas even wound boost down to 15 psi so it’s not over boosting still does it ?

I had a similar problem when mine was overboosting and when the SCV was dirty. A can of Liqui Moly Fuel System Treatment saww the second one fixed, and I turned down the boost to fix the first. Torque was going over 23psi regularly, now it peaks around 21psi.

Since yours isn't boosting as high as mine, chuck in the fuel system cleaner.

Might be worth checking there's no split in the hoses for the intercooler. Look for black oily emissions.

Thanks Tony I will give it a try and check the hoses again at my wits end with it to be honest was pushing 23psi consistently before I turned it down to calm it as I thought that may have been the problem but it has run at that for 12 mths never a problem before just came on instant other day much appreciated
