When I went from ppk and map1, there's minor increase in hp.. Map 2 is much more aggressive. anything is better than 300hp stock to the crank..

Yes, JB4 will spank most other tunes overall. The PPK is far underpowered in comparison, but it's point is that of being factory which sets it apart from others. For pure power, JB is always the one I see that people use.
