anybody advise me on service intervals for 470
what is safe max to chip to.
if your going to chip it get it done properly i think we use prochips guy comes out and does it there and then but its priccy i think it was about £850 to get our 480 done to 550 and its a different truck now. i wouldnt go aboue 550 as above this youll risk damage to the engine and it will decrease the mpg around that figure you should get better mpg and more tourqe on the hills which is what you really want
