Gain ~10whp and ~35wtq on Race setting with 91 gas.

Thanks, but the M235i's have the electronic wastegate and a larger-diameter downpipe, so they likely have a slight advantage over my 335i with the mechanical wastegate (4" dp versus 3.5"). Still, another 3-4 PSI should make a noticeable difference, and for <$300, I may go for this product. I've had Dinan flash tunes in the past and was very happy with them.
