yeah the 02 stock tables are weird compaired to mine. if the effective area is right, and the idle airflow, you want to raise the throttle cracker only if the rpms stay too low. so if you are going 35 mph, put the cltuch in, it dips to 400 and recovers to 1200 and stays there, the throttle cracker is not to blame, it is either the throttle follower or fueling. now if you put the clutch in and it goes to 400 and stays there, that is a problem with the throttle cracker

and more airflow in the cracker means it will pretty much raise the rpm when the cltuch is in

Are your values metric or Imperial? That could be the difference. Also a difference in years.

Yeah, the problem isn't with the rpms going to low, they're staying too high with the clutch in at speed.

I think I just have to fine tune the cracker and go from there.

yeah your throttle cracker values are too high, 2.5 in those cells will make it idle at like 1200-1600 rpm with the cltuch in. put them to 1.00 and i bet that will help
