have you guys tested your meth kit on a dyno after tuning it? I just traded in my Supercharged Cobalt...hade a Harrop TVS Supercharger installed with devils own meth kit and it made a huge difference...but thats with a blower. I wanna see what gains you can get for a NA car. I kept my meth kit for the 370z but not sure if i want to install it now or wait till i put TT in it.
