Well I've given up on issues with smarty and all the updates, so I would like opinions on TST and EDGE JUICE. Both of these units sound great but I would like to hear from someone with a stock or at least close to stock truck that have actually been lucky enough to have run both so as to have a comparison. I do plan on doing something to help with the fuel delivery problem before I go with either upgrade. Truck is a 2000 3/4 4x4 5 speed with an old edge box used as my daily driver and to haul trailers now and then. I bought the SMARTY not to long after they came out, but just never was very happy with it no matter what setting it was on. The edge box actually does a better job at pulling a load down the road than the SMARTY on any setting on MY truck. Like most of you, I would like a little more power, but I prefer more of smooth progressive type. I would appreciate your opinions and experiences with either of these upgrades. Thanks.
