Ok having a little bit of trouble on the new set-up. I am getting a loud pop/miss on hard accel sometimes from a stop or while at crusing speed. When you jump on the gas it pops really loud from the right bank then pulls smooth right after. Does not happen all the time just when it feels like it. Everything and I mean EVERYTHING ignition and fuel wise is like 500 miles old. Plugs read fine and the tune is dead on. Only happnes N/A, on the bottle it pulls smooth all the way to 6,700. Ill post a datalog soon.Mods In sig

 

Kinda sounds like a busted transmission mount.

 

Def engine related. Can feel the car fall on its face when it happens.
