EFI Live LBZ

Got a truck that was tuned with EFI it has a dsp5 switch in it and the guy is wanting to put a ppe hot + 2 et on it so I flashed the ecm back with his stock tune and it will not take the ppe does the dsp5 switch have to be unhooked

Nope I ran for a couple days with my stock tune and DSP installed

Well it goes through the process and then when it says saving stock data it quits is there something wrong with the ppe tuner
