Anyway, Andrew did share with me they are now selling the ESS Direct Flash tune for the 335d. It's a handheld programmer, so not only does actually reflash the ECU the tune is reversable. This is an interesting development since the last time I conversed with ESS their tune was not available for US spec diesels. 55hp gains. I have an e-mail into ESS to confirm that this tune is in fact available for US cars.

If this is true, this would amount to a nice adavancement in the area of true "tuning" options for the d.

Here's the tune...
Curious to know how their opinion on how their tune affects the life of the DPF and th catalyst of the SCR system.
