wellm I installed the gipro today ( not bad to do, followed enclosed instructions and the tutorial from this web site) but I odn't see any great difference, I set it on 3 according to the instructions,, at least I thinkI did :whistle: just sayin;
I fitted one ages ago - and after a week of playing with the ATRE - turned it off and just use the GI bit.
If you're running anything but a standard tune - I doubt you'll notice THAT much - UNLESS you set it to 1. It's then so docile you could ride on ice.
