I know this is like beating a dead horse lol. Here is my question for my wife's bike. It's a 2012 Dyna superglide custom with a 96in engine.Arlen Ness big air sucker,Cobra slip on exhaust and SE 255 cams. This is not a race bike just want it so she has no problems. Now for my ?. Will a SE street tuner be good enough to correct the lean fuel mixture? Please be honest cause I'd rather save my money for my bike if you know what I mean lol. Thanks for any info.

You've opened up the intake and exhaust, and you've changed cams. So, you've altered the airflow through the engine quite a bit.

My advice would be to forget the Street Tuner, which only enables you to flash in canned H-D maps that probably wouldn't match your engine config very closely. You could richen up your mixture, but that's like shooting at a barn with a shotgun.

I'd spring for a TTS MasterTune, and go do a CamTune run and then some V-Tune runs. That will dial your VE tables in pretty closely for your engine config.

A pro tune by someone who knows what they're doing would be best - but your wife would likely never notice the difference.

Another point is that the Street Tuner won't allow changes in the part of the operating range that is regulated by the EPA.  In other words, the part of the operating range most people stay in over 95% of the time.  Unless she only rides wide open all the time, a real tune with a real tuning package is the way to go.
