Old 8 degree injectors, '06 Ultra
Moved this subject from the exhaust section.......
Just out of curiosity, I just checked my injectors '06 Ultra. Imagine that, old style 8 degree injectors. Bought the bike used from the Stealership 3 years ago with low miles. Not being familiar with twinkies, after a month or so I noticed a cold start and a stumble issue at lower rpm's.
Long story short, I ditched the SE race tuner and now have a PV with AT, true duals and Andrews 21 cams. It is well maintained and runs nice, but still finicky on cold starts. I have lived with it, cold is typically not too much of a problem in FL.
I hate to just throw parts at it, but would it be wise to just upgrade to the 25 degree the injectors? Any suggestions are appreciated and I think I already know your answer

If it has the 8s and has cold issues or stalls on slow turns in stock form install the 25s.
Modified as yours is it can be tuning but the 25s will
not hurt and will eliminate the injectors as the cause.
I used to have them all replaced regardless when on the tech line if there were any concerns.
