Every time I give you what you ask for you ask for something else...
Funnily enough I don't store photos of others timeslips, injectors duty cycles, dyno graphs etc just to give you some "proof" and I'm sure if I did it still wouldn't be enough.
But what everyone else seems to realise is that I have no reason to lie, after all I don't earn any money from selling big fuel systems when they are not needed
