are you running a COS?
Post your tune up also..
it is for a 96 k1500 changed to a 0411 from a 2001 express van
Read up on the Custom Operating systems man... COS 3 is what i use.. its got all the special tables for what you want to do.
OS 02020003 is what im using
since your running a 12212156.. thats what you can run..
lemme know if you need some more help..
look in the tutorials, everything is there.
thank you i just need to find the time to read up
Hey John,
Are you using a 4l60 or 80 trans? P.M. me your E-Mail address and I will send you a COS3 tune to get you started. You will need to input your tune specifics into it.
