Message: [QUOTE="Mdub707, post: 693781, member: 107"] I didn't know the "proper" way to flash the FICM honestly, again, bought it second hand so had no clue on the right way to do it. Saw it in more than one place to put the SCT back to stock first. Good to know I don't have to do that. Are those the only two FICM tunes you've tried? Notice any difference between the 40 and the 80? I've only tried the 40 so far, but I like it, noticed the same things you have. Planning on trying it this week hopefully, as long as the weather is nice. That's great to hear, I had read that the FICM tuning was better for stock injectored trucks. A lot of guys were saying with larger injectors the FICM tunes were just causing more smoke and higher EGT's. What size nozzles are you running out of curiosity? Can you comment on your EGT's, or have you not noticed a difference? [/QUOTE]
