hi all

ive my head done on my s2 with a newman cam . mate came round to time it in and it wont ideal so took round block its missing a bit , when i pulled up lifted bonnet turbo and manifold was glowing bright red i know this happens after hard use but only doing 20mph . so i rang a tunner to ask them and he said its retarded timing , never heard off this could any shed a bit off light on this for me .

thanks darren
