I would agree with [MENTION=50]SeoulStinger[/MENTION]. Most of the current options for chipping your Stinger are similar in gains. The main question will be on how much adjustability you desire. TRUE ECU tunes such as Tork Motorsports have NO ability to adjust them at all. On the other end of the spectrum is the JB4 which offers the MOST adjustability via a bluetooth app and almost monthly free firmware updates by the mfgr.
