Hey guys, you are my only hope on helping and me try to solve my situation. So I have a 2017 camaro ss with 14k miles on it. I had a speed shop install an edelbrock 2650 supercharger for me about a 10 months ago. Using edelbrocks supplied tune. Ever since the install the car when cruising around 1600-1800 rpms the car bucks almost like a misfire. No check engine lights or anything have ever came on. So I thought heck maybe it's the transmission recall because I had the vibration as well. So I take it in and they get the fluid changed out for the new fluid and say it's good. Get the car back. Vibration is gone(woooohoooo) but the buck as I like to call it is still there. Edelbrock reassures me it's not in there tune and says it's something out. The speed shop I took it too says they really cant diagnose the problem since the tune is locked. I asked if they could data log it and they kinda just shrugged it off. I would really like to be able to enjoy my car again. Is there anything I could look for or test that would cause the buck to happen while cruising. Thank you in advance for any advice. Might just end up taking it to another speed shop and have them look it over.

The variable cam tables need to be zero'd out, there are 3 tables (low, mid, high). If they are left stock it will cause bucking while at steady state part throttle cruising.

Tune for sure.

That makes since. I wonder if it's something edelbrock missed in there tune? You wouldnt think so butnits definitely possible! Was trying to keep edelbrocks tune for warranty purposes. But the drivability with their tune is horrible.
