Default Anyone else with TPS issues? code 0121

Keep getting code 0121. I've replaced the TPS but it still trips it. A visual inspection shows everything to be fine. The tuner thinks its being triped due the the cam and vacuum and manifolds pressure not being what the pc thinks it should be and that there isnt really a problem he just need to tune out the code. Anyone else with this issue? He cant find a reason for it and the flash file lead him to his conclusion. Anyone else with a 90/90 big cam and TPS issues?

Which tuning software is your tuner using? With EFILive, you will want to go to {C3907} TPS Vs RPM Test Lower and lower the lower thresholds.

same problem here, my tuner is using SCT software. this is essentially what my buddy with hptuners said he was told to do with a car he was fooling around with.
