Why is it that my cars injector duty cyle is only 70% or less under a full 100% WOT blast? 02 mv's during the run are just a tad higher than .700 mv's.

Could this be because my long terms are at 108 in both sides. In my short terms, I usually have a split. I have some csv or datamaster files if anyone would like to analyse.

My car is equipped with 30# SVO, on a 355cid shortblock, with ported heads, XE230/236 cam, and full exhaust.

thanks

injector duty cycle of 70% shouldn't be a problem, just means they're only having to do 70% of what they are capable of to keep up. Not sure what the 02's are suppose to be at but if i had to make a stab at it, i'd guess thats lower than normal for WOT. Hmm, the rest of the stuff I don't know enough yet to comment on, so I won't.

70% sounds right for 30 lb SVO, Mine run at 76% with my 396, But your O2's should be around 890 to 910, That means your running way lean. O2's aren't totally acurate at the goal of 12.9 A/F ratio, but they are cole and shouldn't be that low.
