So I have a 2015 392 and I'm about to get borla atak's and some kook headers. I also want to get the PCM and hand held tuner but I don't know if I'm going to get it dyno. I know it's BEST to get it dyno but I'm planning to do a few more mods before I get it dyno. Will I be Ruining anything by not getting a dyno and just using there hand held for now?
