    Do you guys think that a PPE boost increase valve is okay for the stock transmission? I plan on ordering an edge insight and not running a tune. Just using it to monitor Will the cs2 check injector balance rate or do I need the cts2? Sent from my iPhone using Tapatalk

    Does anyone know if I can ship my injectors to LDS upfront and not pay a core charge? Sent from my iPhone using Tapatalk

    Could I order a tuner that displays valuable information such as injector balance rates, etc, and then use that to flash my truck back to stock... Then just not use any of the tunes that come with it? The only thing I am afraid of is that with the exhaust and intake and tune it might have an egr...
