I had the cooling system pressure tested to ensure everything was working properly with no issues. It checked out fine, and I proceeded to have the coolant flushed and bled while I was at it. The CSF product is installed well and no issues there. Upon further contemplation and discussions with my good friends Reggy, of Irvine BMW, and Dom, of GMG Racing: They suggested the plugs could be the issue. I had swapped the plugs to NGK 97506 one step colder gapped to .20 when upgrading downpipes and installing the tune. With the engine back to stock, I will experiment by reverting to the factory BMW plugs part number: 12-12-0-037-607 and see if that alleviates the random drivetrain malf. The plugs are ordered and we will install them here first thing tomorrow.

OH, and I was glad to find (not really) that I had bent two of my TE37s. Luckily they can be repaired to balance out perfectly, but I suppose the car isn't liking my abuse very much. Photos of the scraped differential cooling fins, after it along with the exhaust made contact with the tarmac after jumping a kerb.
