[QUOTE="itzl0l, post: 14635144, member: 98334"] I had a similar issue, but with 60# inj. Just out of curiousity, what MAF are you running and more importantly how much did you have to adjust the MAF curve to get the car to lambda? In my case (BA3000 and JLT highboost) I had to add roughly 20% to the curve for afr to match commanded.... ...how I fixed my issue: Instead of increasing the MAF xfer ....I reduced the high/low slopes and breakpoint by 20%. Then, instead of massive change to the MAF xfer I just had to tweak it here and there. I know the experts say dont change the injector data (its known good data!) BUT...it worked...resolved both my issues. All I had to do was tweak the timing tables a bit and I was good to go. [/QUOTE]
