I posted this once before with no response, i am currently running 09 FLHT with SE ventilator pc V and vance and hines basic slip ons.
now here is the issue before i changed from stock A/c i juts had the slip on mufflers and they sounded pretty good and I had no issues with preformance. Now since i upgraded the A/C and the pc V with the proper map the bike got sluggish and the muffler sound has completely went from V and H sound to Stock. I contacted V and H and they said its a pc V issue if its not calibrated correctly you will loose sound and HP. I dont know if thats true or not but the engine does run cool and absolutly no backfiring. I really dont know what to do from here should i get the auto tune for the pc V or ditch the mufflers for something else can anybody help????

 

A proper dyno tune to dial it in might help.

 

I should probably qualify my opinion by saying that I have a Thundermax with AutoTune and love it. I dont really know all that much about the PC Autotune module.

That being said, I would try the auto tune before spending your money on a dyno tune. Dont know for sure, but it is probably half the cost of a tune and you can always sell it if you dont like it. Not too mention, you will probably make more mods in the future and everytime you add something you will need another dyno tune if you dont have the auto tune.
