I am honestly thinking that replacing the factory mounts every 10k miles would be better off than dealing with this.

Has anyone tried a solid drivers and factory passenger mount combo?

I have to clarify this, while I did notice this more once I installed the C/S mounts I believe my issue's are tune related. I had a "Custom dyno tune" done at BEHE performance in Eldersburg, MD (Lindsay recommends them, which should change very shortly) and John B. who did the tuning left everything STOCK except for changing one injector setting and raping the PE (power enrichment) tables, which he set to be enabled at only 18% throttle. I will discuss this in a later thread where the tunes are posted for everyone to see.

***Read every VE and MAF table is completely STOCK on a Maggied motor with 8 lbs of boost***

Oh, and as an added surprise, EVERY DTC for lean exhaust, cross counts, MAP performance, etc had been completely disabled. I am lucky to still have a motor.

The mounts let me feel everything that was happening rather than dampening it.
