1 Week in driving the M3 after it started running. I am 385 miles in and the engine feels SUPER. I haven't rev'd the car past 5k or done more than 1/3rd throttle. Engine idles just like a stock S65 and revs wonderfully.
Some small leaks I need to get addressed which could just be power steering or a very very small oil leak.
Finally got the AEM Oil Pressure Gauge working correctly, now I have oil temp, oil pressure, and coolant temp for review during track sessions.
New suspension feels great, the stiffer valving of the MCS 2ways and stiffer springs made little difference to ride quality (which I am so happy about).
Did complete the carbon intake system with adding my Dinan intake elbow (which was previously MS). Now the plenum, elbow and intake box lid is all carbon, can't wait to rev this thing to 8k!
I have 200 more miles before I can get at it and setup a dyno tuning session with Randy from Epic.
Fingers crossed it all continues progressing.
Thanks,
Rubin
