Tune vs weather

[3star2nr]

Hey guys got a question for the guys running aftermarket tunes. How well does your car handle changes in weather and temperature? Assume 93 octane only.

I drive my car all over the country so I've been wary of running a tune since I can't predict if in a year I'll be in 25 degree weather or 110...

The stock Ford Tune is designed to compensate for that, just wondering how the aftermarket tunes stack up.

Thanks

You'll be fine driving in any weather tuned. I dont believe any tune compensates for weather it makes adjustments to fueling, i.e. as the temperature get colder, air becomes more dense, so the maf sees more airflow and adjusts accordingly. This is untouched by tuners and is hardcoded in the ecu (someone correct me if I'm wrong).

I switch to my flex fuel tune from e85r tune for the winter here in chicago since some stations switch to a winter blend and is not always 85% ethanol. In the past 2/3 weeks temputer has gone from 70* to 25* and has snowed and have not had a single issue running e85. Gasoline is more stable and plan on switching to 93 when freezing temps become an everyday thing.

If I were you I'd grab a 91 tune since not all states carry 93. Hope my experiences with a tuned car in varying climates is what your looking for.

Yeah that's perfect! I want to get some long tubes and a tune and call it a day.

I've been hesitant because i like how reliable the factory tune is

Lund, aed, and PBD are the best in the game and their tunes are as safe as the stock one IMO and equally reliable. Outside of those 3 tuners though I personally wouldnt go another route.

Dont buy cheap Ebay headers, you'll regret it! Also LTs can be extremely loud especially if your doing long road trips. I'd hear one in person before you do it, as I did and opted to not go that route as long as I DD the car.

I'm looking at the kooks catted 1-3/4 headers with just an X-pipe and stock mufflers. I know I'm probably leaving power on the table but im thinking that setup will be a good compromise for a DD road trip car

What Chitown said, the tune just adjusts for fueling based on how much air flow its getting, this is why boosted cars do so well in lower sea level areas where air is more dense. If you are interested in a tune, we can get you an incredible deal right now that I know you won't regret once you have driven with it.
