i hear lots of people talking about how they lean out on cold days and even detonate...its this a problem on all trucks or just ones that are modded and/or have a poor tune? i will be getting a '01 lightning this summer and it will be driven year round (i live in central wisconsin) and i dont want any troubles.
lightnings and the cold

I've seen as much as a 3 psi difference due to colder denser air in the winter, thats enough to throw a good tune way off
Some Folks get a separate tune for winter... as for me, i like in a fairly warm climate. not too worried about it
does this only occur on modified vehicles running higher than stock boost, or is it a problem with a bone stock lightning too?
just dont run wide open when its really cold and you should be fine.
In my case that was with a bone stock truck, the factory tune isn't to aggressive so not to big a deal, more a problem with aftermarket tunes
Just a curious scenario question from someone new to programs that are modified and flashed to memory like the BIOS in a computer.
Someone has a tuner device (let's say- SCT X2 as the example) and the tuner setup the parameters for a good street tune and a aggressive race tune.
This person changes all equipment back to stock and wants the stock Ford tune. How does he get back to that original tune flash??

simply select "return vehicle to stock" or something along the lines of that on the x-cal 2 handheld device and it is back to the stock tune.
Aint that assuming the x-cal 2 being used removed the stock tune in the first place ?
even in my cobra i wouldnt dare of doing any high speed runs in the cold
stock is no fun :nonono:
I havnt been around these truck to long but am confused by this. I have several friends with 500+ 03-04 cobras, and I had a 03 with 520 RWHP and never had a problem with the cold. Are the Lightning computers shitty and can not compensate for the cold? Or are the tuners running them too close to the edge? I feel like there should be no reason to have a winter and summer tune unless the tune is so close to blowing?
Neither is venting your block :nonono:
Yea but your truck is basically stock. it's when you change the pulleys around you need to be careful.
most tuners do a cold weather tune and hot weather tune but still say to keep WOT runs in cold to a minimum if at all.
I'm running 4lb lower and won't push it if it's under 60*. but i dont have money for new block.

What do you all consider cold ? below 40 ? below 30 ?
03-04 Cobras aren't plagued by sh***y rods like the Ls are, so they're more forgiving. Also, as I'm sure you are aware, cooler air is more dense. Cold air is extremely dense... more so than MAF can calculate as it rushes past the sensor. Since the MAF reads less air flow than what is actually coming into the motor a lean A/F results. Having tunes for both cooler and warmer conditions simply allows for a person to maximize power "safely" regardless of the outside temps, so he/she doesn't have to compromise power in warmer temps for the sake of safety in cooler temps.
just curious, where in wisconsin are you? and where do you draw the line on when not to stomp on it?
would a wideband be beneficial on a stock truck that is driven in the cold weather?
