Hello I was wondering if i should do the DINANTRONICS Sport Performance Tuner. or the JB+ both are simple plug and play but the Dinan is $100 more because of the bluetooth iphone app. My far has the N55 engine.
here are the links to both.
iv heard that the dinan has a better chance of not getting caught with warranty issues.
