Wow! this input is really appreciated, thanks to everyone.
This reply drags on a bit so a warning to you all.
Before I read the latest responses (last night) I had the urge to
test the original MAF (as I knew it wasn't happening with this one),
well I was right, no power loss.
This other MAF however caused the truck to drive like a slug (as it used to) with little or no boost. I might be completely wrong on this but I can only assume that the problem wasn't obvious back then due to the overall poor engine output and now with the new sensor installed its raised the boost levels enough for it to cause an issue.
In reference to 'OnPatrol's' suggestion, I wish it was as simple as reversing the hoses, I had a look at my vacuum layout and found that all was ok.
I too had a
snorkel fitted some time ago and have seen some shocking work done by 'so called mechanics /fitters'.
I've also checked the factory manual and confirmed that these hoses were ok, I'll
check the whole vacuum system soon.
Another stab in the dark is that with the old MAF, the fuel pump didn't need to deliver high amounts of fuel so it didn't 'struggle' to keep up with load. Since the new MAF it may have caused an increase in flow rate causing it to fail. This theory isn't very strong as one would think that this would also occur during hard acceleration and not during cruising, also when throttle is backed off and re-applied the pump has no issue with supplying required fuel.
I called about 10 different dealers and a few private mechanics and the best I could get was 'you'll need to bring it in and that it would be caused from:
Turbo system
Fuel pump
Accelerator potentiometer (fly by wire system).
Cheers.
