so i have a 2002 2500hd lq4 and im swapping in a tbss/zo6 cam so im going from 196/207 .467/.479 to 204/211 .525/.525 both @ 116 lsa my question is will i have to get a tune right away or will i just be running rich and throwing codes? how rich and will it be drivable untill i take it to a good tuner? and who should i get to tune it?

 

it will prolly run a lil bit lean, not rich, that would be an easy cam to tune for, see the sponsers on the right side of the page for reputable tuners, it will be driveable tho without a tune, but a tune will make a big difference

 

thanks i appreiciate it
