We have received 2 Smarty 3rd gens so far. More on the way about the first of the month. I have been testing it on one of our trucks and the results are first class. Just on level 5 with the TST on level 4, the power is very impressive. I will be testing the upper levels tonight to see what power is made. We have our modified CP3 on this truck and our Stage 3 injectors. The Smarty with these mods are showing to be a perfect fit. We have been testing with a DRB3 hooked up to measure rail pressure and we are finding very good numbers. Better fuel mileage is also a nice suprise with this product. This thing IS a gotta have product. Thanks
