I think the theory is that the OBC will now be less useful than it once was, as its being fooled with the amount of fuel injected

My car is so much quicker, my trip home from work was really enjoyable on some fast A and B roads, I will have to watch my speed though as its really easy to stray above the speed limit...................I imagine my next fill up will reveal that my mpg has gone down

Question is, am I going to try the top setting at some point?

Good to hear you are happy with the performance now. I dug out my user manual but it doesn't mention anything beyond E2? Does your chip housing have a ds013 label on it?

I have factory settting B1, Tuning 1 D1, Tuning 2 E2 and Tuning 3 F4

So E2 is your maximum setting ?

How weird that I have 4 settings to your 3, my manual is nothing like yours either
