Could white smoke at start be caused by tune

[Timbo126]

I know white smoke at start is usually either due to a bad FCIM or stickage. My FCIM is getting plenty of power which really only leaves the possibility of stickage. However when it was smoking at startup i had an IDP street tune installed. I just purchased and flashed Matts SRL tune on and now it doesnt smoke at start up anymore. I do have a straight pipe as well. Could the tune have been causing the white smoke.

By the way The SRL tune seems to have way more power then IDPs street tune. Also it seems to have raised shift points to just about 4k rpms. Has anyone noticed also that the EGR temps at idle drop a lot faster with a tune then they do when their stock?

alright its FICM fuel injector control module and EGT exhaust gas temps, not egr or fcim but that tune should not have anything to do with the white smoke at start up have you changed what kind of oil your running that could change it with the injectors being oil fired

Yes the smoke can be a result of tuning. Erics tunes do fuel more agressively cold than most

Sorry about the mis abbreviations that was due to the lack of attention since I was trying to simultaneously pay attention to a lecture while writing this thread on my iPhone. So my appoligies there, however back to my question I am using Rotella 15W40 but will be switching to mobile 1 5w40 synthetic next oil change. I was under the assumption that the smoke could be due to an increase in fuel with the tune as well. Truck has 68k miles on it if that makes a difference.

Rotella t5 or t6 10w30 will be far more cost effective than mobile one

Schaeffers would be too. And a quality oil at the same time. I wouldnt run rotella in a 6.0 if I was paid to do it.

Wow really I have been running t5 for a few years and its been good to me but I do like schaeffers oils

I usually run plain rotella T, but I have switched to t6 in my 6.0. I've never run anything but rotella in any of my trucks, and after dozens of great UOA's, I don't see the need to ever run anything else.

[Dave]

Every time Ive run T5 my stiction issues come back

Unless something changed over the last year neither t5 or t6 are real synthetics anyway

[scparrish]

I didn't start with stiction issues so that may be the kicker but I agree you can't go wrong with schaeffers
