Jb4 on the 320 is the best. Stick to map 5 if you want to play it safe. It will adapt performance output to whatever supporting mods you have as well. So adding a catless downpipe or larger intercooler will better your performance in map 5 as well.
Always look at your oil temp in a turbo car. Never gas it heavy till the oil temp rises. Jb4 or not.
I’ve been jb4 for 2 years, dinan before that. Jb4 is the best piggyback. A miracle for the 320. Personally, I haven’t come across a faster tuned 328i. It also outruns stock 340i/35is. The 320 also loves meth or e85z, or just some good ol 100 octane.
