Error code p0174 bank2

[1979mustang]

I just had Pypes True Dual Exhaust kit and Pypes Polished Shorty Headers installed on my 2008 4.0. And the check engine light came on, had it checked and the error code came up p0174 bank2, and was told I have alot more air flow because of the installs and the computer is throwing it out as an error. The code was cleared out and has not come back on. Was told it might come back, and should get a Tuner and reconfig the settings.
My question is, is that my only option, or are there other options out there that would just fix this problem, if it comes back.
Thanks

I don't think it will come back, when clearing codes you put the computer back into adaptive learning and it will adapt for "extra" exhaust flow. Theoretically you should not need a tune for shorty headers.... theoretically.
