I am wondering if anyone on the website has put De-catted Harley headers on their 2014-2015 RGS. I have them on my 2015 RGS along with Cobra 4" mufflers and an FP3 with the Generic tune flashed into the ECM. The bike is running pretty nice except for the decel pop which I just changed to level 2. That should remedy that problem. I have also run an autotune for several sessions and flashed that. The bike is really running pretty well. My question is, has anyone used a different map with this setup even if the mufflers are different than Cobras. I've been told most 4" mufflers are not going to be that much different in flow with mild upgrades. I haven't installed a hi-flo filter yet because I didn't want to run too lean until I get the A/F ratios adjusted with the De-cats. I've also been told the De-cat headers are similar in flow to the V&H Powerduals but not exactly. Any thoughts or map suggestions on this setup would be appreciated.
