Just installed my "old school" INTENSE intercooler core. This particular model does not have provisions for normal PCV function. I already have a valve cover breather, so went and installed it last night.

For those of you who have ran an intercooler and used a breather, how much did you have to modify your MAF table to adjust for the vacuum leak and the lean conditions at idle/cruise? I was adjusting my MAF table quite a bit last night but still seeing very high long term fuel trims.

Any help/recommendations related to this are welcome. Thanks!
