Interesting! My tuner said that the maps on the tune could be perfect and i will have no issues, but i need to monitor the air/fuel ratio once driving to be safe. i guess its all up in the air right now...

You just need to make sure the fuel isn't frozen in the line, and the fuel map tables in the ECM give the right amount of fuel for those sensor values. |

Oh and yes i have an oil pan heater, not a block heater. There was no room for a block heater with the turbo manifold and such.

Really? A heater that replaces a freeze plugshould work for you. Though I guess at this point you'd also have to drain the block and pay for additional labor to install it and however much additional coolant to replace it would require. :P
(edit: did have a link to some freeze plug heaters in there, but the forum is screwing it up for some reason.)[This message has been edited by dobey (edited 12-31-2014).]

I saw the link before the edit, thank you., yeah where u can install that frost plug heater is right where the turbo manifold is. no room, we could install an in-line coolant heater directly into the coolant lines...but according to my research we wont need one if i have an oil pan heater. So i'll see how the engine starting goes in the winter with the oil pan heater, and if it needs more heat (which i doubt) then i'll get an in line coolant heater i guess. haha.

Well, assuming the coolant doesn't turn to slush, you won't need a coolant heater. 
You might be OK with just the pan heater. Hopefully the coolant won't get slushy or freeze, in the tubes under the car.

i hope not either, but it has never done that too me yet with my old engine, even when i forgot to plug her in. plus a block heater doesnt quite heat up the coolant in the tubes under the car though right? just the area around the freeze plug. At least thats what i read.

Well, the block heater heats the coolant that's in the block. Since the coolant is in direct contact with the heating element in that case, heat should pass through the coolant back up the tubes. But the coldest point of the coolant in that case will be the furthest point from the heating element, of course.
If you haven't had a problem so far with the coolant you're using though, you should be fine.

The factory temperature compensation curve should work just fine. Air doesn't change because you're running an aftermarket turbo.

But the ECU isnt factory tuned...like i dont think it had a factory tune file in it, bcc when we first started the engine it ran like crap...thats what im worried about.

The ECU must have had a tune in it, otherwise the engine wouldn't have run. It ran like crap because many things about your engine are different from the factory engine the ECU was tuned for, so it was probably using the wrong amount of fuel, possibly getting a few readings wrong, etc…
