In diesel power mag a year or so ago they had some proven power cobinations which includes chips, injectors, and intakes to get great power. I laways love to read TDR revies of turbos and of course I am curios what people are doing to make horse power. I am still working on putting my 4bt into my Scout, but when it is done I plan on playing a bit with it. Intake yes, injectors yes(which ones), exhaust 3inch or 4, and ve pump mods. Anybody out there with a good recipe? Crew Cab what are you doing to make 250hp reliably? Forrest Nerring, I loved your post about the 12 valves, do you have a 4bt recipe?
