HI

I have a stage 3 large turbo Escort Cosworth approx 330bhp , want to go to approx 370. I know the best way fwd is a live map on light blues /greys by MSD but this is not practical at the moment. Why is it u can't buy a chip of the shelf to run light blues on a standard spec engine (upgraded head gasket) ???

Might be a silly question but if you can do it for Dark Greens why not Light blues.....(I appreciate it will need a proper set up)

Thks for your views..

Cheers Malc
