Grams/second is showing me 5.1406 after I made the change and now it will idle ok, but when I drive and after like second gear it is bogging down like it is getting too much fuel. I changed my commanded afr table B3605 and now take a look.

and you said before that you took a few tunes and made yours. what is that Main VE table from? 5.3L or 6.0L? You have a 6.0L right? Also you should upgrade your OS to an O2' OS. Personally i would run COS3 so you have to boost VE table.

I dont think he has one man. I was inquiring about getting one. If i was you Will i would be ordering one right now. That way you wont have any question for us if you are running lean or rich. You will know this and you will be able to get your Ve table correct. If your Ve table is incorrect then you may be adding to much fuel in certain cells or at a specific Kpa. Im not trying to push you into getting one because i think its important....its the most important tuning device you can have along with the scan tool.

Well I am planning on getting one, but right now I need to get the truck running right again so I can drive it tomorrow. I guess I will just have to go back to my old tune.

With Russell's tune it is the same thing. Still idles fairly rough and when driving I give it gas and just bogs down and will not move like too much fuel. LT's still at 25%.

Alright as a further test, it looks like my idle and bog down problems lie with my IFR. I changed it back to 29.9 and it is running good, but I am getting TONS of KR and at partial throttle, I only have duty cycle of 32%. Here is a log with everything tuned and IFR at 29.9.
