Nahhh, I don't mean stock pipe, as long as you have a decent 2.25" system... The ECM = ECU - same thing, it regulates the valve, but as far as I'm concerned, the regulation should be identical to a CP1, as said the regulators - just the duty cycle tables will need changing.
People need to look at what I've said in the past in multiple HDi threads about the valve train on a stock HDi, there's one part of them that will cause issues... Technically it isn't even related normally, but due to the weird low friction design of a HDi, they're like they are, this can be fixed with a simple modification that doesn't really cost that much and is a relatively cheap modification in the grand scheme of things. I've mentioned it countless times on here I'm pretty sure, but simply looking at why I'm saying exhaust manifold pressure and high inlet pressure is a bad thing and looking how the HDi head is designed, you will see where the problem lies. I'm pretty sure in the past I've even told people straight how to fix it!
If the lifters themselves are STILL an issue (though I cannot believe they are) I'd say try and increase oil flow to them.
