Thanks in advance.
What do you find missing from the stock 335? Remember BMW tuned the car to feel like a NA engine, having never driven a turbo car before my 335 I have to say I find the engine behaviour in the 335 very similar to my previous cars.

The JB4 is a great tune and easy to install, I'm sure you love it (it does add a noticeable kick)!! I'm running mine with some hifo cats/intercooler and have to say the car on the most aggressive map (map 5) feels too fast for public roads, I potter around on the most conservative power map (map 1) .

As for "Crushing reliability of the BMW"....Plenty of people on here will tell you not to run a 335 without a BMW warranty due to Fuel pump/injector/wastegate problems on top of the random steering rack lock/DSC failures that seem to affect alot of E90/92 BMWs
