I know you have to install a jumper on the memcal, but I dont know what all has to be changed as far as tuning goes because the only write-up shows 7.4 tuning values. I just need some basics to get my motor up and running with a TPI tune since it has a 4l60e. There are alot of factors to be changed because it isnt stock, Like I said I just need a base file to get me running and then i can actually tune. This is all kinda new to me as far as TPI tuning with a TBI ECM and .bin file.
