Stuttering at highER RPM and low kPa

Hey guys,

 

Well I'm having an issue with the engine being choked out (I think) of fuel and stuttering at a certain RPM/kPa value, usually just lightly touching the throttle at about 65-70 mph in 4th gear. Unfortunately, I do not have a datalog for some stupid reason, but I do have a video. I believe it is a tuning issue, but I just want your guys' input on what I can change. There is no sharp increases/decreases in the VE table, and my brother and I tried to tune the spot with no success actively tuning the VE table. Thanks again guys!

There are a few things it could be. It sounds like you've already tried editing your VE table, but the ignition advance could also be off.

 

However, I had a similar problem at one point and it turned out that one of the injectors that I was using was no good. So, you may want to test your injectors.
