Car is running 13.5 AFR's on boost and 12.5 up top according to MAP's tailpipe Wideband.

My car has always seem to run a full point leaner on the dyno from DB to MAP. I think Jim said his always does this as well, anyone else see this?

It's lean but not stupid lean. On DB's dyno it was 11.5 up top and here its 12.5. We are going to shoot for keeping it consistent obviously...I will check it against my wideband after I install it next weekend. I saw 1 2 count of knock and that's it...that was in spool up as well which is something else I need to get sorted, but otherwise up top it was a clean pull. I am not too worried as long as knock isn't there.
