367 and losted alot of bottom-end. I went from turbo to standard in my Nova FMS to lower the cooling head and lost no noticeable power. I know turbo plug engines are harder to tune, so that should give you a good indication on how efficient it's combustion chamber is. Just my $.02
Sounds like you were using too cold a plug. Most turbos (even the hot ones) are designed for onroad and just too cold for offroad, thus the poor bottom and difficult tuning. Find a hotter turbo and all will be well.
