this is all 93. WHP. Dinan is crank numbers.
A stock m2 makes 325 whp on 93, do your homework before making claims.
From dinan website "F87 M2: 383 HP, 411 lb-ft of torque." Crank... so its 337whp. How is that same as a 235 with mods?
A stage 4 big turbo Dinan m2 will only make 400whp, with a DP maybe 415whp.
Actually only 380whp, see below:
