I have a 2012 Chevy Cruze Eco 41K ish miles Trifecta tuned (the middle one, advantage? I can never remember). It's had the valve cover replaced, my spark plugs are gapped to .028 and it shakes kind of a lot, I think. I took a video. I do apologize for the relatively bad quality, I just took it with my phone.

. I have the intake resonator deleted, secondary cat gutted, DDMWorks Short Shifter, and a muffler delete. I also have stiffedned the motor mount with window-weld. (The mount wasn't bad, but, stiffer is better, right?) I'm really curious as to if this is normal or not. I've read that 4cyls can be a little shakey. I've only owned 6cyl cars (e34 bmw with LOTS of mods and a 2002 VW Jetta vr6). I'm sure there are a few other mods, but, that's most of them. I haven't done any electrical upgrades, however, I do have two LED strips on the inside of the car in my footwells (one for driver and one for passenger). Thanks for the help! I kinda hope this is normal for this motor, I also do need to datalog for trifecta, but, it idled rough before I trifecta tuned it, too.
