As title really any kind soles out there willing to share?
I have power commander fitted and a piper cross sausage filter

I know something as small as different air filters can make an impact but it would be a starting point for me

Thanks in advance

I took my laptop with me, and tweaked it during the test. I actually had to change the values of the map for both low and fast idle test. It was set to around -40 for fueling in the lower throttle position settings. Think that's 0‰ and 20‰
