GF Performance Chip FOR JK

[The2000Yankees]

Does anyone have the "GF Performance Chip" installed or had experience with with it? Can anyone give me feedback on it? Does it really work? Also, I have Superchips with advanced transmission tuning installed on my 2008 JK X, can the GF Performance Chip work together with Superchips or I have to uninstall Superchips tuning before installing the GF chip?

just to answer your question. there is a lot of skepticism on this part. it should be noted that when something sounds to good to be true, it aint true.
