Roush Phase 2 low speed drivability issue

[Eljay52]

I have a 2016 with Roush Phase 2. Didn't run the Roush tune vert long before I had it dynotuned by JBA here in San Diego. I do occasionally have some serious surging at mild throttle in 2nd gear around 3K-4K rpm. A few times it really bucks as if I'm on and off the throttle. I'm going to ask them to look at it.

I just got a Phase 2 car recently. My has the surging a little bit while cruising in the 2,000 to 2,500 RPM range. I had another car that did that and they turned of the EGR system to resolve it. Did the custom tune resolve it for any of you. I'm planing to get a VMP tune soon.

VMP tune completely got rid of the surging for me. Transformed the drive-ability 100%
