Im just wondering if bad cats could give faulty readings and also throw the CEL saying im too rich when i might not really be.
You already stated you were too rich so why would the CEL get thrown saying you were rich so you likely are. How about posting your mods and tell us what the AFR numbers are at? I'm running around 57-58psi at the rail and am using a tune for 450's. Mark
PS: MY AFR's are 11.5 or lower due to this tune that was for 450cc injectors when I was running TORCO.
