This would be great considering the cost of the mechanical upgrades supposedly needed.

Bm3 is very sensitive to octane and intake temps.
Running stage 1 93 (stock), I had alot of quite large knocks, even on supposedly good fuel, and had to drop to the stage 1 91 map.
MHD have stated in threads that a dp is mandatory for stage 2, but that an intercooler is optional depending on climate, but they have a stage 2+ that needs an intercooler (not sure how this equates to Bm3)
Unless you are living on the Arctic, I would definitely do the intercooler - our cars pull timing from ~115 degrees. On a 3/4/5 gear I was seeing intake temps >120, with an ambient of 55. (stage 1)
Honestly, you'd be insane to run the car at stage 2 without going FBO imo.
