I don't really think the tune is to blame as it has worked well for awhile on this tune. I know what you mean about the afr changing slightly at idel but it seems to be having lean spikes and that is when it is felt thought out the car.
I have checked for vac leaks already but I could have missed it, if there was a vac leak tho would I not see a high number in the a,b,c,d fuel learning tables?

I'm waiting on a new bpv ago I will be able to rule that out in a few days.
