If you have a engine failure with a tune ,can you put the factory tune back in it and get away with it or will Ford know what happened?
void the warranty!
Installed the 90 performance tune yesterday,all I can say is what a difference!
it really woke up the turbo and actually set me back in my seat a little,very surprised.
I know it’s been beat to death,but I need to know what you guys with the unleashed tunes,still run the original spark plugs?does one step colder plugs really make that much difference?
With the tune will it shift through all the gears in D or just in sport mode like stock tune?
where I mostly fill up at has 90 octane
do I get the 89 or 91?
So what’s involved with the tune for the engine?
change thermostat and spark plugs? Is that it?as far as the engine goes?
does the heater still heat good in the winter?
I have 2021 ford ranger
i don’t know anything about the tuners on the market,is there one that’s simple and helps with getting better gas mileage?
im getting 20-21mpg,normal driving
