Need advice on modding my 335is with DCT.

How old are the injectors? You might have one clogged or not spraying very well.
Did you install port injection yet?

Just dawned on me the STFT's are up since I added more ethanol and didn't give the ecu time to adapt before logging.

Update: The car is down on boost (peaking 24psi) but still ran some very good times at the track. I installed the Walbro 535 today and I'm hoping it can handle straight E85 or at least a much more concentrated percentage. Would like to avoid mixing this spring but most importantly the advantage of more aggressive timing from the higher should help at the track.

I like the idea of just running straight e85 for now and avoiding blending. Considering the DCT is likely unhappy with over 600whp (maybe less), my thoughts are to mod to 600whp for now over the winter.

With the idea that I might want to push it a little further in the future if I decide to update the clutches, what LPFP should I go with? I don't want to mess with meth if at all possible, so which LPFP will make my life easier but without going too big and wasting money?

Will a stage 3 with dual 450's pull it off or do you think I should go bigger?

Any suggestions with the build? Anything I'm overlooking regarding the catch cans (I've ordered one) PCV mods, intake filters (running BMS dual filters), or anything else of substance? Thanks

Stage 3 with Dual walboro 450's should work.

You should look into upgrading your HPFP, if you are going over 600hp.
