SSBPGSR

has anyone has any experiance with a stutter box. i am running uberdata on my boosted GSR and i talked to my tuner. he can make a stutter box, two step, FTL, whatever you want to call it but does not recomend it, for reasons he will not tell me. i was just wondering the disadvantages of this, i know the advantages. its a 100% daily driver street car. GSR boosted on 8psi. stock GSR tranny. i would like to try it out.
