Black smoke??

[Adamvabeach]

WHen running custom tunes is more black smoke when accelerating good or bad? The spartan Aggressive street ECO tune I run blows only a little black smoke when I get into it, or I can let the turbo spool up before going and it will blow black smoke but not whole lot.

Black smoke is just unburnt fuel. It inst really good or bad. Its only bad if its excessive. (Like sitting at a stoplight smoking)

It usually usually causes higher EGTs. Do you have a EGT Gauge?

you would normally want little or no balck smoke on an econo tune. Course, mine smokes nicely in econo!! ahhaha

Adam some smoke is normal. A decent amount on hard acceleration on that tune was normal for me when i ran it

Nick it's bc your trucks ragged JK

[Adamvabeach]

cool thanks, I did't think it was really bad but just wanted to make sure.

If I lay into my truck real hard from a stop i can smoke out half a block

my understanding is that turbos need velocity to work, and the hotter the exhaust the more velocity it will have, and if you have smoke the smoke particles are carrying heat and keeping the exhaust hotter so it has more velocity to spool the turbo.

idk if its right its just what i have pick up over time from ppl.
