$400-$500 Tune for 80whp. wow is all I have to say.

and just like anything with a turbo theres always the question of reliability, personally if i had that car i wouldnt be tuning it that amount without beefing up the internals first otherwise you are just asking for trouble in the long run

Not as reliable as Japanese but the warranty is second to none. BMWs come with factory warranty which covers turbos, drivetrain, and more up to 4yrs/50k miles or certified pre-owned warranty which also covers turbos and drivetrain 4yrs/100k miles(lasts several years if bought used or renewed after factory warranty expiration). Countless amounts of people are running tunes (up to 80+whp) tunes without issues. Better MPG is a result. Also, there are MAP levels where you can lower the hp thru the steering wheel or iDrive interface. But without warranty, the 335i is just not worth it.

Full bolt on 335i's roughly push 410whp 420ft/lb tq give or take.

The tune is also plug in play and can be taken out in about 15 min. before going to service.
