Your really going to make me count aren't you....
28 current reported instances (4 of which reported after JB4 install) see below
-Not saying JB4 is root cause (one guy said it happened with Cobb) but it seems the tune may overwork the transistors on the MSD80, which there has been a service bulletin about this particular DME
I figured being a vendor you would be a little more understanding but guess not!

"Well installed my JB4 on my 07' 335i (88k miles) after replacing my spark plugs. Drove nice for a bit, got home, played with some options, decided to give it a go while it was warm, probably shifting 2nd to 3rd or 3rd to 4th not sure its an auto, and all the sudden my car gets shaky as hell and low power. Throws the exact codes as in the OP's post - "

"It happened. Installed JB4 G5 ISO two days ago, car drove just fine for two days. On the third day car was just fine, I get almost to work and im going like 20mph in 2nd gear, I go to accelerate and car falls on its face. Pull into parking lot, Misfires on 1, 2 and 3, along with 30BA. Clear codes, restart car, still runs like shit. 30BA. Guess I fried my bank 1 mosfets."
Maybe do some research before flaming a post
