After driving the truck some more I have to say the new turbo really is rather good! I'm not sure if the ECU has adjusted or the turbo is running in but the low RPM performance really has made the truck a lot more fun to drive. The lacklustre performance at low revs and terribly slow turbo spool have always been the problems I'd assumed would be the most difficult to address with this engine so this is a very welcome improvement. It's actually viable puttering up the windy, hilly roads where I live in third gear under 2000rpm now. I'm seeing 10PSI by 2100rpm which is also a definite improvement. And this is with just with factory fueling so I'm starting to think this might all end up in a better place than I had anticipated Really quite encouraging to see how much this engine has been improved without adding any fuel. The gains from the 2.5inch exhaust, intercooler and improved turbo have stacked up quite nicely.
