The engine management light came on during my test drive! The fault code was a fuel pressure that was too high. SAC said they could put a better model chip in that did not have this problem on DID's. I said no thank you. Like you I do not like them.
I notice my Gen4 as with my sons Triton (same onboard computor) that one must take the on board computor stats with a pinch of salt / and / or realize a factor with which to correct it by. When on holiday it indicated 7 to 8 km/L which horrified me. I really nursed it and got an indicated 10km/ L but by the next reading was back to about 9.5 km/L still nursing it. Actual worked out to about 9 (on average while refuelling) which I was still not happy with.
So when I got back I started investigating. As with my previous Pajero's the valves were way out. (I think the mechanics bluff that one). Ran quieter but not the big improvement I was looking for. Next checked turbo boost - it was down - got it up to just below spec. Better but still not what I would have expected. Did the EGR & decat while I was busy in the engine bay. Again no serious improvement. I priced the SCV and was given a price of about R790.00. At that price I think it is worth trying. Also they seem to be a general problem. I also see a higher pressure SCV is available. I am dubious about such.
I would appreciate working with you in resolving this - you are in Centurion aren't you ?
What I did notice was that the turbo on the gen4 is a lot smaller than the Gen3's. The boost spec is the same though. My thinking is smaller turbo less lag but less top end. Not that the Gen3 had lag - it was brilliant. Are we not maybe trying to squeeze blood from a stone ? My son disagrees about turbo size. He says it works the other way round. What says you ?
You have gone a long way in improving the breathing on your Pajero. Would definitely be interesting to compare notes sometime. Yes I am in Centurion. We must make a plan sometime soon.
Have you checked out the inlet manifold for gunk on yours? That is probably my next big job on the engine. I am also contemplating a new timing chain and guide as it seems there was a recall on overseas models on this but not here. At R790 a new SCV is also not a bad investment at our mileage so will also look at that sometime.

PS maybe you must book the TITD trip in your diary to really compare notes with some other Pajero owners. Bug Roelf for some details. He might not answer too fast though, he is now driving a slow tractor bakkie after his Ferrari/Pajero.
