Hi friends. I just landed myself some hens' teeth i.e. E28 M5 motor i.e. the famous M88.
Now, I am pleased with the 280bhp it produces. However, I would love to have a bit more power, without forced induction. What tricks can I play around with to realise a bit more power i.e. 45bhp addition.

Hi

Expensive to tune but standalone, intake from zaprace, and some cat cams should do that easy only about 2k in parts

From what I've read the removal of the AFM and running a piggyback management system like Unichp Q gives good results.

ShepsEvo3 on here is the man in the know, he's just tweaked an E28 M5 with great results.
