I know H$S and Spartan tuners can still be had out there for an arm and a leg. Are there any other options remaining to get good power? I already have the delete portion handled with the mods in my SIG, but I would like to get some added power. KEM said they no longer support DPF delete, at least with anything that is shift on the fly. Any recommendations? I want good power for daily driving, but the ability to turn it down to a safe level for towing. Are Spartan and H&S the only options remaining until stocks run out?
