I have just bought a 2014 SG and i'm going with D&D Boss Fat Cat exhaust with the perforated mufflers, i want that loudest they have. Which tuner should i buy, the Power Vision on Thunder Max? I'm not doing a lot to the bike other that a Stage One download once it comes out. The bike stock has more motor stock than my 96B that had Woods 777 cams and and Power commander 5.

 

So did the D&D Boss Fat Cat exhaust come with both locations of O2 sensors? If it only has the ones (12MM) located down by the transmission the Thundermax wont work as it requires the large O2 sensors (18MM) located up by the heads in the pipe.
Are you getting the bike tuned or going with a downloaded map? If getting the bike tuned ask the tuner what he likes to tune with.

 

t-max but it is 2010 choice, not sure about the 2014.

 

I havent ordered anything yet. i know im getting the Exhaust and talked to them on the phone to make sure they make the exhaust for my bike. Not sure what tuner i'll get cuz i know there isn't a lot available for my bike yet cuz its new.

 

I have a 2013 CVO Roadglide. I am running the D&D Fatcat. It has both sets of bungs 12 and 18, I also have the Powervision. I am having trouble getting a proper tune with the PV. I have a friend who swears by the thundermax. May try the thundermax tuner if I can't get the pv tuned to my liking.

 

TMax is a DEFINITE step backwards on any bike with TBW. The stock Delphi is THE way to go... adjusts fuel on the fly (no accepting a tune change), removes timing when need be, etc.

Tuning is WAY more than adjusting VE tables and some are finding this out. I am fairly certain if you had your bike tuned... the issues would go away.

 

the Power Vision won't work on 2014 yet. I doubt the Thunder Max will either. They have a different plug on the ECM in 2014 I think it is the same as the 2013 Dynas and softails.
