Hey i recently purchased a yamacharger for my 07 apex and im wondering how much i would benefit from a pc3, pcv or rb3 tuner and ignition module, and if anyone has maps available for the yamcharger and exhaust mod, any input on the subject would be greatly appreciated. I have access to dyno in my area and just want to know if its worth it to purchase a tuner and get the sled tuned on the dyno for a $150 an hour
