Mike - your sight says out of stock on JB4. My new to me 09 E92 335i 6MT feels like the timing is retarded in 1st and 2nd gears. It also feels like the ECU has a mind of its own despite my efforts at throttle modulation. Throttle response is not as good as I would like so I'm hoping a JB4 will improve it. When will you have these in stock again?
