I have a 08 silverado and i was thinking if anyone nows where i can find some o2 sims for sale or where to buy them

 

Your best bet is to get the PCM tuned and have the rear O2's turned off in the tune, check some of our sponsors like Wheatly or Nelson or do a search for Justin from Blackbear performance and they could do that for you. Or you could buy tuning software like EFI Live or HP Tuners and do it yourself. O2 sims have been outlawed and are hard to come by...you'd either have to get a used set or get them somwhere on the "black market".

 

what he said..

 

get a Wheatley tune and you will be happy.

 

still thinking of it so dont have faith in me guys cuz i will have a tune on my truck but i have a friend that has hp tuner and he doesnt know how to remove the rear o2 on my truck or his and do anything else and i have been reading up on it so i can get the tuner from him and do it myself but i get confused on some of the stuff to do and my truck is new and dont want to mess it up
