I?m swapping my 1995 S10 with a 2001 6.0 out of a Silverado. I?m super new to this tuning stuff been watching a lot of videos on how too?s. I?m putting a T56 behind this engine which the pcm was originally tuned for a 4L80. I wanted to do segment swap to get all the data for the manual from a 2001 LS1 Camaro but the segment swap option is grayed out why?.... I have deleted all the VATD and have modified the MIL DTC section in my tune. I still need to tune for a Tick performance street heat stage 3 cam and 630cc Bosch injectors. I changed the flow rate vs. KPA but I don?t know where to enter the rest of the injector data. Please help me get this tune straight going to trying start my engine soon
