Hi guys newbie here and to tuning.
I have a 98 k3500 with a 350 an 0411 pcm and an 02 express base tune, that I had starting and running normal, I built a 383 and changed the cylinder displacement and injector sizes in the tune. It runs pretty good it just wont start without throttle pressure applied. once it starts and runs for a few seconds it idles fine in park and in gear, A/C on or off. it just refuses to start without cracking the throttle open. warm or cold doesnt really make a difference. every once in a while it will start when cold but idles at 2-300 rpm until it finally picks up and idles normal. I have replaced the used injectors with a reman'd set and the problem still persists. please tell me where to look.
I have searched the site and not been able to find out how to change the idle during startup/cranking.
Thanks in advance for any help you guys can give me.crewcab 383.hpt
