Impressive dyno collection. Nice that you have taken the time to compile this list.
Maybe my 360whp goal doesn't make sense. Let's look at it another way...
I want to add at least 25whp over a stock M3.
With any luck my planned mods (TMS pulley, dry filter, GIAC software and Supersprint cat-back) will get me there. I would consider removing the secondary cats but I don't want to touch the primary cats. This is because I don't want added noise or smell and I already feel bad enough for how un-green the M3 is
