I am currently running 5 star tuning economy/ perfomance/ towing tunes on my 2015 Ford F350 6.2L GAS. In performance mode I get a very noticable increase in HP and throttle response and lower fuel economy. In economy mode, I get better fuel economy and truck shifts up quicker. Its about the same HP wise as well as throttle response. I havent tried the tuning tune yet but will soon. I am considering adding a k/n cold air intake and was wondering what I can expect from combining both of the intake and tuner. And how is the intake without any tuner. Thanks

 

You can expect nothing but added noise. Cold air intakes will do nothing for you performance wise. Save the cash do a different upgrade.

 

What kind of noise?

 

Sucking air noise. Tons of threads out there on the cold air intake deal. I almost got one myself until I did some research. I am 5 star tuned as well.

 

Many OEM intakes have been "cold air" intakes ever since they stopped putting the ring air filters directly on top of the carb. Why wouldn't a manufacturer spend $20 on plastic tubes and drill a hole to be able to advertise all the benefits that come from not sucking hot air form the engine bay?

Someone might need to chime in with the exact location for the 6.2, but IAT should be part of your MAF sensor setup, you can check intake air temp after the air filter and sometimes see an increase from aftermarket filters that actually pull more air from the engine compartment.

 

I have the Livewire TS+ with tunes from 5star & have one of the gauges set for intake air temp on my 2012/6.2 & the intake air temperature runs within 1 degree of the outside air temperature shown on the dash. A "cold air intake" isn't going to do any better than that. They are a waste of money IMO.

 

my intake temp on my livewire is never accuarte

 

Maybe your IAT sensor is bad. What does it read & under what conditions?

 

If its like 85 outside, its usually saying something like 91. i dont know if this is how its suppose to work, but when it gives you the value it holds that value for a few hours. for example, if it reads 91.08, it will say that in 3 hours even though the temperature did change outside and the truck has been started a couple different times within that time.

 

Mine is constantly changing. Not big swings, but by a tenth or hundredth of a degree one way or the other. Your tuner may need a software update or something.
