My AW 1M
will be delivered in 2 months and I'm thinking about installing my PROcede V5 after the brake-in period. I have used this piggy-back unit on all my N54 models (335iA, 135i, Z4) and I totally believe its the best aftermarket car part I have bought, ever!
This, however, doesn't mean that it will be the perfect tune for my 1M...
I have been searching all the forums and the rest of internet for answers but it doesn't seem to be any Vishnu tuned 1Ms published?
The car will also have Akrapovic Slip-on and N55 midpipes.
Please give me your opinions and experiences.
