Tuning After 233/233 Cam I just got my TSP Torquer Cam 233/233 595/595 cam installed. After getting the idle to settle down I took it out for a logging. I am using FlaskScan for logging. I am getting a lot of KR. The highest is at 2000 RPM(max 7.7 @.44gms/cyl). My Average O2 data at WOT (no WB) is 929/909. My average O2 in cell 22 is 861/839. Sorry for all the data but I have KR from 1800 to 6400 and need some help. Should I change my timing or should I increase the fuel? My VE table is stock. I have always used the IFR table for fuel and PE for WOT. Should I change this method? I did a log before the cam and was getting some KR but not as much. My WOT timing is 26 or less. I did increase my timing at idle which did help with the idle but did not change it anywhere else. Looking at my charts before and after it looks like my timing has gone up. I guess I will start looking at the timing first. Sorry for such a long one.
The car does run great and can not wait to get it tuned right.

Looks like you're lean in cell 22. I bet that's where the kr is coming from. Right now my 02s are in the 920 range(still rich) but I think I'm not gonna go too much leaner until I get it on a wideband.
