rough idle

[blown 04]

I hope someone can shed some light for me on a issue im having. my tvs 2300 6.0 with a gt2-3 cam has kinda a rough idle, now I can smooth it out by using the bi directional controls and moving the afr to around to the 13's. is this normal? my way of thinking is it needs more fuel but how do I achieve that running closed loop? sounds like I have a air leak but my trims are close from bank to bank. Also truck has no throttle response till almost pe enrichment. I posted my tune

log your IPW, 13 afr is rich and will cause the idle to be rough. remove 20% from your fueling table. also tune it SD you will be better off

Ok will do, what will this tell me? I know 13 is to rich but it make my motor run smooth, it seems like I have a air leak but cant find it.

^ look at your MAP sensor in the log it will tell you, aim for 15-16 at idle and also check your timing at idle should be in the low 20's
