BEST TUNE FOR -4F WEATHER

[rdodger]

Up until yesterday i have had extreme street loaded and thought i would switch it to my canned 65 hp tow tune due to the fact that its been really cold up here in Ontario , Canada and on extreme street the truck seemed to smoke alot when starting in the morning . this morning when i started it on the tow file it smoked for a min but stopped alot quicker . i really dont like using the canned tunes but i also dont know if running the extreme street in such cold weather is bad for the truck . if anyone has any input or similar issues your help is appreciated .

Sorry bud. For me, cold is anything below 70*... When it has gotten colder, I have actually switched to lower HP tunes just for the simple fact that it generates less unburnt fuel until the engine gets up to operating temperature. It's likely that is exactly what you are seeing out the tailpipe.

havent had the truck in that cold of weather but i have had a lot of luck with the the srl tune down to the single digits and it doesnt smoke much its still a lot of power just less smoke on start up

SRL or Extreme Street is fine in those temps.

just wondering if i should load the extreme street again or leave it on the canned tow tune . which one do you guys think would be safer for the truck ? i'm not racing anyone in the snow , i just love the tune and want whats best for the truck .

Run Xtreme St. Just dont beat the truck till its warmed up.

i figured that custom would be safer than canned i just wanted to make sure . thanx
