M3 Rematch...
I was at an F8x dyno day and with a JB4 (which I believe is around $600-800 not bad at all) and E85 these cars can hit just around 500whp with a baseline of 412-420whp
On the same dyno same day my old LS3 C6 put down 395whp, a bolt-on e90 M3 put down 360whp

Are they the new style or older style? Im assuming this first pic is the new one and the second is the older?
Or
Do you warm them up real well?
Mine dead hooked after a nice burnout but then again that was a bolt on 97 ws6
