I have a 2004.5 Cummins 4x4. Looking for the best tuner for a little extra towing power. PPE or a Smarty?
EFI is not for the 2004.5... I have used Smarty for quite some time and have been happy with its performance.
PPE has the customer service of a corpse. If you call there and talk to Doug, you'd be better to wash out your mouth with a revolver.
