W210 E55 vs M3
Nice kill. I've seen the new M3 to be about equal to a stock W210 E55. It kind of depends on who gets better traction off the line. With my PowerChip ECU, they are no match but traction is a big problem
I never dyno'd but they claim something like 17-20 peak HP. I did G-Tech before and after and conservatively dropped a tenth from 0 to 60. The times were much more consistent after I got used to the extra power. Rolling into the throttle is a hard to learn technique! Also, the car now spins the tires wildly (without ESP) during full throttle 2-1 downshifts. The mid range is awesome!
Is it worth it? For me, yes.
