My personal choice is the PCIII, but I have riding buddies with the SERT and their bikes run great, too. It depends more on what builder/tuner you choose. One dealer near me uses only the SERT, while another uses only the PCIII. Most of the local indie shops in my area recommend the PCIII.

 

If you are going to tune it yourself get a PC3 if you are going to have a tuner work on it ask him which he prefers, mine said that he could give me a much better tune with the sert.

 

Thank you all for the info. I'll ask the tuner at the h-d shop which he likes. THANKS AGAIN, Mark

 

My pc3 I had on my 06 dyna was hard to cold start4 to5 turns of motor before starting and use to pop on back off tried 3 times at local dynojet dyno tuner to fix but never really got it right . Ibrought a2007FLHT and brought SE race tuner (Sert)for this bike. Itstarts onfirst turn to top dead centerand no pop on back off.
