Idle/etc is all the tune. That cam should have good idle. As for the trailer hitching, that is common with larger cams and most of it should be able to be tuned out. What RPM/etc does it happen? I hope people explained that cams have trade offs like that, which is why I suggest stock or baby cams on FI daily driver applications. Stock cam could have easily maxed out the motor/drivetrain and made 800rwhp with no issues. Just turn the boost up.
Log maf, map, timing, o2 sensors, rpm, tps, etc.
