I had some documents from AEM when I got their WB controller setup that for turbo installs they recommended some crazy 34" to keep it from overheating... That's around where I put it (around area behing RH half-shaft), but I think it's way too far back. MS seems to constantly play catch-up, makin it surge around idle, irregardless on using ms steps or ign pulse. I can tune a ms step to work great, but then all other RPM's are shot. Gonna try moving it to the original O2 location and see if that helps. I remember on my GN the damn O2 was close as hell to the turbo, like 2" on the DP... but it wasn't a heated O2, if that'd matter.
