I having starting issue with aem ems. Could it be the tune? It having a hard time starting when it is cold but as soon as i plug in my stock ecu, it fire right up. Anyway to adjust this myself or i got to get it retune?
I heard that aem ems have starting up issues from some threads.

Does anyone know a good tuner for aem ems in san diego, ca?

 

9 out of 10 times it's a tune related issue.
