what are the 335d tuning options?

Just came back from test driving the 335d. It was great....for a diesel, but performance wise I wasn't that impressed. What are the current offerings for performance sw and piggybacks? What kind of wheel hp/torgue numbers can these engines produce with a tune?

I would say
*ECU flash
*sprintbooster
*sporty air filter
Unfortunately US 335d are tuned down in comparison with European ones because of restrictions on emissions. Not to mention the fact that 335d's Steptronic never launches in first gear unless you use it in a manual mode.
That's why the 3 options above are not options, they are a "MUST HAVE"

You should have a browse of the UK forum - the UK leads the way for diesel tuning, especially with the 335d. Most members are running 285rwhp (350bhp flywheel) and 515lbft torque calculated at the flywheel (measurements off a Dyno Dynamics road)

There are one or two piggybacks available, but the best solution is by far the ECU flash.

Some threads for you to browse:

hey
now have been on dyno two times.

firts time try to get so much out as can with DPF.
results are: about 320-325hp and about 660nm.can get more but then DPF start get dirty very very fast.so i do not beliewe some countryes cars have so much power with DPF.maybe get little bit more=more shit to DPF and dyno shows more than here...

second time DPF away,3inch downpipe.
361hp and 780nm.now propblem is boost start increasing itself after 3000rpm=wastegate too small.

next:
have to increase downpipe size to 3,5inch and exhaust pipe to 2x2,5inch.
port westgate.
this way could get broken 400hp.torgue to higher rpms maybe also more.not down because gearbox.

What flash are you using?
changing parameters after every hardware change?
