Racechip piggyback (F30 328i)

[andre320D]

If you want I will go dyno my 330d next week to show you figures. It does make a difference.

What car are you wanting to chip BD_O?

A 428i (posted here as the 4 series forum is a bit dead).

I decided to stick with the proven tuner, so BMS it is - just need to decide between Stage 1 and Stage 2 now (see my other thread).

I have driven my brother's one, 428i vert and it moved. maybe something wrong with your one.
Good luck with the tuning tho:thumbs:

Eh? I don't get your post mate. What would lead you to suggest that there's something wrong?

:smashScreen::hammerhead: Misread your post. Sorry man
