Stage 2 M340i - 500hp on stock turbos?
Ive seen some tuners claiming 500hp on stock B58 turbos with stage 2 and E85 fuel. Is this realistic or are they measuring at the crank and exaggerating?
My M340i is currently stage 1 at 430hp. Want to go stage 2 but only if I can get close to 500hp. Otherwise ill wait and do a turbo upgrade.
