I'm tempted to try this on the M5. Run some logs and send them to Terry for good measure, and receive a clean bill of health before romping on it.
He said near 40hp give or take depending on conditions, and should be fine with other mods like downpipes. Also mentioned he had not heard of any codes being thrown.
I was thinking:
-BMS tune and Can Bus Cable to clear codes: 25 to 40whp $500
- AMS Down Pipes (Catless) 30 to 40whp $1800
- K&N drop ins -5whp lol $100
So for under $2500 you've got an extra 60 to 80 or so HP. If stock cars are making over 600 crank hp, this should nudge you close to the 700 mark. Not bad...

Same thing I am thinking, but doing AMS catted (for noise limits on various CA tracks) and BMC filters.

Right on. So no issues at +3! Good stuff. I am assuming that Terry has looked at your data logs?
