Rpm's at 800
I have installed on my 2011 AT the stillen headers/cats, the akropovitch full system, and the k&n intakes. I also have a base tune from uprev. The car rpm is a little above the 500 line and is a little shaky. I've read that some of you have raised the rpm to 800 when tuning the car. Why is this? Will it reduce the shaking? Thanks
