My point exactly. Marco worked on yours and squeezed every last drop out of your truck that he could. But that tune only works for your truck. That tune probably wouldn't work so well in thebignasty's or mulisha's truck. Hence the custom tuning that is needed. They need it to squeeze every last drop of power out of their trucks as well. Every truck is different, every engine is different, every injector, every ecm, every everything is different between trucks. That's why yall need custom tuning. And that's what we've been getting at. Marco has obviously cracked the code and knows how to tune it so why hasn't he gone and given that ability to everyone else. To keep a strangle hold on the market, afraid of reprucussions from people blowing their engines up? Who knows. Point is is that custom tuning is needed for the CR's in order to extract every last bit of power, performance, and reliability out of them. An off the shelf tuner isn't going to allow that. The smarty is great, no doubt about that, but as with all great things there is always room for improvement and the next stage is fully custom tuning.
