Actually, I think all tuners are carp at this point except the Smarty. Big injectors and a good pump will get you enough fuel, the smarty gets me timing. ink the Quad is more for guys running less mods in their truck.
The difference in the fueling with the Quad and without was really noticeable. I throw a ton more smoke without the Quad and it pulls so much harder too. I think its probably more for trucks with less mods, not really a competition level piece of equipment.
