Yes it can be done easly.

Would I be right in thinking that with something like SM4, you could still get away with lots of boost in the midrange, then link EGT's to extra fuelling so that if it was held open for ages like Mike is talking about it simply got richer and a little less powerful to stay safe but was full power in short bursts when EGT's dont get out of hand?
Why just loads of boost in the mid range

you dont see my engines running less at the top,
Biuld a Cossie right map it right and then fit it correctly and there is no problems.
