I asked about the predator triple play and the duramaximizer, both claim low EGT's and no/little smoke and the other thing is no reflashing the computer and no trace of use am I right about the edge EZ is similar? What are the differences between these type of power adders in the way they work? I have read tuners add fuel at idle and cruise but the other kind dont and dont raise egts beyond oem tolerences.........I like the code reader,clear,speedo correction of the tuners but this truck was 42k and I dont want to blow my warranty or LBZ and I'm thinking an exta 100hp and 200ftlbs is enough for me as I have a hot rod to drive if I want to scare myself. Whats the deal?
