I am hoping somebody can help me out with a map for my stage IV Pro build. I have a:
2014 Street Glide Special
SE PORTED AND POLISHED HEADS
HIGH COMPRESSION PISTONS
58 MM. THROTTLE BODY
HIGH FLOW INJECTORS
SE 259E CAMS
SE STAGE I AC
FREEDOM PERFORMANCE TRUE DUALS.
PC V WITH AUTOTUNER
Any help is appreciated.

That Stage IV kit will always have rideability issues until you get it on a dyno and in the hands of a tuner that knows what he is doing; dealers can't tune them properly. This is a common issue with the Stage IV builds and the 259E cams; a map won't cut it.JMHO

Absolutely...it must be put on the dyno. However, I have to break it in beforehand. Therefore I need a map...do you have one?

I don't have one but a friend has a map done by one of the best tuners in the country; only difference is exhaust. I will contact him as see if he will share is map. I will contact him today; send me an email address; my email is longtaind@att.net.
You know, a good tuner can breakin the motor on the dyno. A proper tune will take 3-4 hours and a good tuner can have the rings seated in the first hour easy.
Get it to a qualified experienced tuner for proper breakin and calibration development. IME worse thing is to ride the bike without a proper recalibration developed on a dyno while monitoring temperatures and load.
There is no way for a rider to assure proper breakin EVEN with a second hand calibration from a different bike as no 2 bikes can be expected to run properly from a borrowed calibration since there are so many variables such as injector +/- 10+%, exhaust systems (huge fuel requirement differences between systems), and cam profiles...even between the same p/n cams.
Steve Cole did a lot of measurements from advertised data sheets to actual measurements. The results are virtually every cam mfg uses there own way of measurements even when stated as same as another mfg.

This build (stage 4) requires a completely different mapping of the EFI than anything Dynojet has published maps for.
That said, someone there may have something in their personal databases with a map that may work to get the bike to the tuner.
IMO there is no way to cheap out or shortcut this build and should be taken directly to a tuner and not guessed at...damage will occur if not close in fuel and timing.

Star Sarge,
I have the map and am sure it would be very close as the build is identical to yours except for the exhaust; he runs a Fatcat. Problem is the map is in Powervision format and I don't know of the PC V will recognize it but a call to Dynojet would answer that question.
Still think a good tuner is the way to go; he can seat the rings in 20-30 minutes. However, if the PCV will recognize the Powervision format and you want the map, PM me an email address.
