Hi Stu...

This might be a silly question but are greys really on their knees after 400bhp? I am not questioning ur knowledge But I am getting really confused over the way to go above 400bhp. I know every tuner has thier own individual way but if a grey can't fuel it , it can't fuel it for anyone can it??

As I say I might be miles off but just need it clarified please...

Thks for your advice as always.

Cheers Malc
