hey guys long time reader here first time poster. hoping for some help should be pretty basic hope you guys can follow.
I have a 86 chevy k5 blazer running a 99 vortec 454 and a 4l60e. before you start in about the 4l80 . trust me I know but the customer swears the trans can handle it.
first off could not do a segment swap on the vortec 454 pcm to remove and replace the 4l80 program so I decided it would be easier to install a
vortec 350 4l60 pcm and retune for 454?
so far trans works good still need to change a few things but the engine on the other hand is not happy
ive looked at the differences between the 2 files and swaped every table I could find but made it worse.
im hopeing to start from scratch and reloaded stock vortec 350 tables back on and try again but I am not shure what to change and what not to.
