I have this customer's car in for a tune after doing a blower cam, headers etc. Car runs great, but he did complain of a 2-3 shift issue from the prior tuner when the car was stock. I did a run and put the shift points and speeds back to stock. I can see that on the 2-3 shift the TPS is closing. I have shift speed and rpm set lower than this. Not sure what is going on.
