Dinan gets around to offering ECU upgrade for BMW's 335i
While other companies have been at it for a while (ahem, Vishnu), the Dinan crew is able to offer something that other tuners haven't: a warranty that coincides with BMW's own. The cost, however, is steep, coming in at $1,999 for the reflash alone. Piece of mind – and tuning products for BMWs overall – doesn't come cheap, but for those who want to extract the twin-turbo'd inline-six's full potential, this may be one of the best mods to date.
Thanks for the tip, Dmat!
