Well to tell you about my truck first, 1995 f250 5speed, i was told the turbo was upgraded when i bought it but it looks stock to me, its a garrett 1.10a/r (although it does spool alot faster then my freinds powerstroke) It has intake upgrade and 3" downpipe to 4" straight pipe that exits infront of the rear pass tire so its running leaner now that the turbo can breath...
I have a Edge chip for it and dont have gauges yet so i run around on economy mode most of the time,
well i turned it up to Extreem/Race mode once to see what it would do (never on it long without gauges) No Smoke at all? i would think i would have a little smoke, not that I want it

but I think there should be a little right?
is there a way to turn up the fuel?
sorry if its a dumb question im new to powerstroke's im used to cummins
