So i did my blue spring upgrade kit after installing my sct 65hp tow tune. But now the pedal feels stiffer. Its not constant in the stiffness either, itll be stiff then once and awhile it will be normal. What could this be, anyone have this issue and fixed it?

 

The go pedal is only hooked to a electrical connector, there is no mechanical linkage, there is a spring on pedal to give you the feel so if it is truly getting harder to push then you might have something like dirt or even the carpet making it harder to push.
