    hey guys new here and need some help. i installed a vortec 5.7 into a 98 s10 along with a 0411 pcm. we have been trying to figure this out for some time. when truck first starts cold it runs very good maybe a little smoke from fuel im guessing. after it warms it starts to smoke of fuel badley. should i follow the auto tune post above or am i missing something. i am trying to run a 2002 express file for the tune. thank you in advance for any assistance you can provide. by the way i have efi for this build but am not very savy on tuning.

    so went through auto tune instructions but i do not have a wideband. i did notice right side o2 reading higher voltage than left. engine runs great with throttle but terrible at idle. i messed with ve tables today lowering them which seemed to help smoke but had a hard time idling. any help is appreciated.
