Gonna get a new CVO Street Glide and want to know if getting the 117 stage 4 kit that now has the heads is a good choice? My plan is to get V&H power dauls with high output slip ons and a TTS tuner. The dealer said I would still get my 2 year warranty if I did this with the bike purchase. I am gonna be traveling with this bike more then around town. Gave up dirt track racing for this new hobby so I'm a power hungry type. All the help is appreciated either way. Warranty is not my concern the usability of this second addition Stage 4 kit is though. 
Thanks Allot
Bill
If warranty is of no concern, do not waste your money on a dealer installed stage IV kit.
Low end TQ is less than stock, its complete joke.
My .02 cents on a good bang for the buck Touring upgrade is as follows.
Suburban Speed 124" Mahle piston kit. .030 head gask.
Tman 226 or TTS 200 cam (when it becomes available)
5.5 injectors, Valve spring kit. (Stock heads and TB are retained)
Good exhaust and mufflers, (mine)
Good AC, the stock Ventilator is junk.
TTS tuner.
You will need a clutch upgrade to handle the low end TQ. Because this combination of parts
will stomp the HD kit by 25 Ft pounds at 2000 RPM.
Sorry if your one of the Guys who payed good money on a dealer installed Stage IV kit.
You were mugged and robbed in the low end TQ department.
