Hi,

I will attach the file pulled directly from my car with a Kess along with the stock map i got from the internet. I've compared to the original and can see it's tuned however I'm not experienced enough to tell if it's a good tune or not - I understand a lot of diesel tuning stuff but not petrol yet. Could someone look and see what they think please?

The car drives very well however the supercharger boost divert valve opens gradually up to 20% at high revs (6000+), I've been told a good tune should divert no boost at all.

Any pointers / map locations would be appreciated to help me learn.

Hi,

Yes Simos 8.4 ECU. The ORI is a full dump and the one pulled from my car is only the part that KESS V2 reads, the part containing the maps should be the same.

Thanks!
