Thread: 383 bogs down off the line at WOT.

    OK, all of theses changes have it running much better. However, not the original problem is back. Bogs down off the line with WOT. I have adjusted the "AE vs TPS Rate of Change" and the "AE Correction vs TPS", but this still occurs. Problem is all the forums say "adjust", but I'm not sure "what" to adjust. I've attached what I currently have. I have increased the "Rate" chart on the far right quite a bit and smoothed out the line. For the "correction", it used to go in a straight line to a negative value and I've flattened it out on the right side. Am I in the right area? Again, I just need more gas when I hit it at the light from idle. (Goes very lean.)

    Check your AE vs TPS/MAP RoC Blanking values from post #11 above.

    Those are set correctly. At least 5 & 5.

    IF the Base Fuel Table is tuned (Fuel Graph blended smooth), the AE vs TPS Rate of Change is sufficient, and the AE vs TPS/MAP RoC Blanking values have been lowered, then I don't understand why there's still a problem.

    Again, here is my question. How do I know the AE vs TPS is sufficient? Did you look at my pics?

    Of course I looked at your pictures; that's how I know your AE vs TPS Rate of Change is sufficient. Actually, it's probably too much.
    My 508 engine's AE vs TPS Rate of Change is shown in this LINK. I can't imagine why your 383" engine would need so much more AE.

    UPDATE: So, that last close out was not good after all. I finally found a Holley certified mechanic. He took the throttle body apart and found that one of the four injectors was not plugged in from the factory. Two years and countless hours of Troubleshooting, but it finally runs correctly. So, remember, it could be the equipment! Thanks for all the help!
