Well probably but anyways, I recently loaded some pre made tunes using EFI into my truck. Now some things are going on that either are weird or I wasn't expecting. For one, My SES light came on, Checked codes and I got P0234 and P2122. Also, here is what my dsp is supposed to be set up like. #1 - Stock, #2 - Economy, #3 - Tow/Street, #4 - Stock, #5 - Stock. HOWEVER, on my DSP switch (and using my scan tool) the first position is coming up as Non - DSP and then second position is coming up as DSP#1 then 3rd is DSP#2 and so on. that confuses me, is my economy tune in the 2nd position or 3rd? also, on all positions on my dsp except for the 1st (non DSP) my transmission shifts hella funny. is this what people mean when they talk about de-fueling? Because, when i am driving regular, my truck has a "gap" between shifts where there is absolutely no power for like half a second but when i get on it, it shifts better. is this normal? BTW, SES light stays on no matter what i put it in now! thanks guys!
