Proform 850 dialing it in closer
We see a full second delay from the TPS going to wide open throttle 59 until the rpms rise at 60. Real???
Top gear is looking good. Second is drifting rich maybe a 1/2 AFR ? Its also starting at a lower rpm - not sure that matters other than the engine isn't usually working as hard at lower speed and lower gears.
I'd make each change, one at a time, get a couple of passes on each before deciding what effect it had.
What's the emulsion set up in each block? If you tell me its more than two .028" holes per well then you know what I'm going to suggest..
Understandable. No big deal.
I don't understand why this is happening, especially the low end.
