    That’s the route I went. There are some EPA files that are better than others, but they all suck compared to any of the non-US market ones. Pick anyplace on the planet except the US or EU and start looking there for files. They don’t have the EPA, CARB or EU Tier bs in them and they run pretty good, even without playing with them beyond the flash.

    No numerical order. I have an Excel spreadsheet. PM me.

    EU is better than US at the time of early ACERT, EU had less stringent Nox standards=better timing. Australia files are little more smokey and remember they don't have near the elevation so file doesn't compensate as much for it.

    My BXS has the Aussie 550 BrakeSaver file in it and 57’s and a fuel temp resistor. It’s a little rough at idle with code injectors in a file engine, but beyond that it runs great. You do have to watch it at altitude though. I’ve had it get pretty hot in BC a couple times, but usually I can torture it and it barely breaks 1000*.

    If you still have the compounds remember the Pyro readings isn't same as single for safe point. Heat and energy is lost going through both turbine housings. If I remember right it is about around 250° difference on average, but don't have access to TMI anymore to look. All that being said is those monotherms can take more heat, but they don't dissipate heat as well. Everything is a trade off.

    That’s what I was told, 200*-250* depending on ambient. I try to keep the BXS to 900*-950* but the 5EK’s and the mechanicals get warmed right up regularly. The B and C don’t even start to run until you get them up over 1000*, but if you can keep them at 1050*-1100* will they ever pull.

    On dyno on Singles ive seen minimum of 200-250deg and up to 500Deg Diff Before and after turbo Depending on engine rpm & Hp & turbo design etc Compounds would only be more diffrence i assume unless someone has tested and proven there isnt more diffrence

    No doubt there’s more temp drop through the twins. Hard to say how much though, it would be different from one installation to the next from the different manifold and turbo configurations.
