Why? See my post above. I ran the 451 RWHP 5.0 with my 335i with only a DCI, tune, meth and dps which at the time made only 16 psi and around 400 RWHP but still managed to creep slowly on the 5.0.
The density altitude was high that day (around 80 degrees at Big Willow which is 2,300 ft above sea level) so the turbos certainly helped me on this run.
