1) What are the risks of using tunes and how can I mitigate those risks if I do tune (ie don't run a 93 tune? etc..?)
2) How do the tuners hook up the truck!? I have a power outlet, some usb ports and an audio jack, but I didn't see a plug tuner in here port :P
All tuners can "potentially" void your warranty, if your dealer is a stickler for such things. The level of tuning you use wont really matter.
and although you can return a truck to stock by erasing the tune...the dealers starscan can tell if the ECU/PCM was accessed by a non-dealer device.
They cant prove exactly "what" you did...they just know it wasn't accessed at the dealership level (All Starscans are linked to your VIN)
So you cant say it was another dealership that erased and reset something 3 times over the past month if they don't have it on your VIN's record.
At best you're only adding about 25 HP with a Gas Tuner...not nearly enough to kill anything.
The Dealerships are primarily cracking down on Diesel Rams that can be tuned to add 100 HP + and up to 300 ft.lbs of Torque
...Those are the guys breaking $#!+ that are making things harder for those of us with minor mods.
I have never heard a tuner for a 5.7L 4G
1) causing a problem, 2) being identified and blamed as the source of a problem 3) Warranty Voided due to unauthorized use of a Tuner.
It doesn't mean you wont have an issue...just that the chances are very slim.
I've returned my 4G Hemi to stock for an RRT Re-flash of the computer at the dealership and they never saw anything, or did and didn't care.
If I was in for a problem related to something I "broke" though....perhaps they would have dug a little deeper..I'll never know until that happens.
It's a risk I'm willing to take for the benefits I'm enjoying.
All Tuners use the same port the Dealers use to access the ECU/PCM,...the OBDII port under your dash near the steering wheel.
