Not the gains on paper I was hoping for... But feel VERY nice, much stronger low end and keeps pulling. Got about 10 hp and torque more... Will post dyno and photos tomorrow
thats not a bad gain after you already gained a ton with mods alone, over all thats a huge gain, the best thing i would look for in a tune would be the power across the entire band rather than just peek HP, waiting for graph in hope to see what im looking for...
there was +25 torque gain in the some of the low end.

And you're telling me this now??? thats a huge boost in the lower band and thats one gripe iv had with our motors stock, the lack of tq in lower end, the thing that differentiates us form the stock 335i is the lack of low end torque.
Those are great numbs for a HR with intake,exhaust,tune! you should be able to really tell the difference, seems like you gained about 40whp and 25wtq from stock which is some gain imo on these motors!
im in for the tune for sure now! thanks for the info share
.EDIT: just realized that the stock dyno was done a day back and perhaps a different dyno so that would affect some results and edited gains

It is widely known that Church dyno is very generous. The before and after gains are what you should focus on. The results of the intake and pullies were at Stillen and not Church, correct?
^ i know that is why i was amazed at the delta power and not really by just the actual numbers. if they used different dynos then that would make a difference and thats perhaps what i missed, i knew it was impossible, so he gained delta of 20hp and 10tq with mods plus 10tq and 14hp with tune so total delta power change of 34whp and 20wtq that is more believable but still generous gains!.

Pics hopefully tonight or tomorrow... Got it back on, just wish the Clips on the ionic grille were better!
Ya, 333 is the dyno pack... I would assume true to the wheel is right around 300... I was at 291 at Stillen without the tune not on a dyno pack. Feels pretty good and now officially all done modding!
