Thread: 3.4" Pulley?

97autoxvette, do you have a wide band O2? its possible you are leaner then you think. also i have seen lean conditions before boost and entering pe that start a condition for you to kr. if your maf tuning make sure you dont have any major spikes or dips in the data. also make sure your timing table is also smooth and not major dips or spikes.

Good points, I can double check some of my tables. I do have a full-time AEM wideband that I use which shows me good conservative AFRs. I have not changed the MAF at all, I only modify my PE table for AFR purposes. I will take a look at my timing table this evening and see how smooth it really is.
