I'm trying to see if this is just my imagination or do I have a part throttle stumble? My car was recently retuned because I added the progressive linkage. The secondaries don't open until after 2000 rpm as you can hear in the video. My issue is that the engine isn't as smooth as I would like from idle to around 2000rpm. I'm thinking I need to add a bit more gas and/or timing between idle and 2000 but I wanted to hear what you experts thought.
