got a mail order tune back in the spring, and was going to install it with my headers. never got to it before going to basic. i'm just now getting around to it. headers went in fine truck ran fine. put the new computer in... it fires on maybe 2-3 cylinders then dies. it did this several times, don't know what's wrong? tried getting a hold of the guy i got the tune from several times, no answer. is the tune bad? or am i just missing something here?

 

im assuming its a different pcm since you said you've had it for awhile, did you do a security relearn?

 

yes, it's a different pcm. no, how do you do one?

 

You can try this.
