So I am brand new to this tuning stuff. I am using the Dynamic EFI P4 EBL and TunerPro. I did my engine swap, my initial tune was surprisingly good and after a couple VE Learn runs it feels good. Although I do not know what it has in it.

My low speed VE table looked good. It seemed to have 2 craters in it but I smoothed them with 1 run of .4 smoothing.

My HIGH speed VE table is where I have a question. It drops off aggressively above 3600 RPM's Driving it I do not feel that aggressive drop off but I also have not pushed it hard or hung in upper RPM's as the engine is brand new.

Will I have to add values manually? VE learn and keep the RPM's in the upper range longer? If I were to add them manually how would I imagine those numbers? Just bring the table up to a smooth curve and see how it works?

Not sure if the info is needed for the question but engine is 383, Lingenfelter LPE219 cam, 1.6RR, AFR Vortec 190's, Edelbrock High flo TPI base with Super Ram

I'm attaching both the low and high tables. Take note when looking at them they are from different angles. The low speed is increasing RPM's left to right. The high speed RPM's are increasing right to left. I spun the high speed around the better show the drop off.

 

Not necessarily an issue just because it drops off

ve will usually follow the shape of the torque curve. Airflow demand is highest at peak torque which in tpi / superram cars is very strong in the 3200-3600 range

also there can be power enrichment effects at wot that can be adding to the fuel curve that may make it look alittle more drastic of a fall off than expected. Check those values

going thru high rpms in wot can fly by pretty quick so may not be catching all the action going on. I mean it does look like it falls faster than i would expect but hard to say. I would keep trying up there, maybe higher gear pulls to slow the rate of acceleration down to give more time to collect data. Means higher speeds so be careful
