Hey mate no under no load just instant loss of power no mods that I know of.
Apparently had full engine rebuild in 2019, set of pistons and rings, conrod bearings, head gasket, set of injectors, new sump, new clutch.
It’s a manual and struggles through all the gears, if u keep the boot down in any gear once it gets over 4000 rpm the engine management light comes on, I have a boost gauge and it gradually gets up to 15 psi.
So if its instant, like the motor is trying to shut down, it sounds like limp mode. These motors are real picky with over boost. Is the intercooler original? Crimped ends on the core, or welded? If they are crimped, even if its not, remove the intercooler and check it for oil spots, particularly on the underside. If it is, the Intercooler is leaking boost. Leaking boost you will lose a fair bit of power. Look at this and report back.
I'm thinking over boost & limp mode.
Get a cheap OBD scanner & the Torque app for your phone and check your boost, that's a cheap convenient way to get a second 'boost' opinion.
Those scanners wont work with the Di motors. ECU talk is the only option. What worked for me on my old Di to overcome the overboost limp mode nightmare was to buy the HPD billet high flow MAF housing. I went from 16psi on the dot hitting limp mode to going to 3 plus psi boost and still no limp mode. Wasn't cheap but I no longer had limp mode issues. I really don't miss the ZD to be honest....Quote:

So going by your response - meeting me was a good thing - or I would’ve got a ‘yeah dammit’ response haha
I’m with Mudski, check the intercooler - if it’s an original crimped end style 99.9% chance it’s stuffed , get a welded end type , I got mine off eBay & wasn’t that pricey & still goin strong , also put a piece of clear hose from the filter outlet to the injector pump & check for air bubbles in the fuel . ANY bubbles will cause you grief .
Ohh I think we'll just leave it at that? Haha!Quote:
