I have the Diablo Sport (A recent addition) that has made a vast improvement in my supercharged JK. Mine came from HESCO (that created my supercharger kit). The performance tune load has made my vehicle a joy to drive again. It shifts like a normal vehicle now, the engine "feels" a lot more powerful, city street driven hills that used to cause a downshift (plus many times a TPS lightning bolt) now are driveable in 4th gear and I have yet to have my first TPS trip since the download.
I recommend it!
