If I buy another ECU to tune my car but when I take my car into the dealership I put the stock ECU will they know I ever Changed it? For 2014 charger rt with a lifetime warranty.

Yes. The dealer will detect that is less than a heartbeat. It's already 370 HP.. what do you want beyond that?

That's like saying why wouldn't you want 707 horses in a charger.

The systems used to diag a car that dealerships use can and will tell everything about the car even if it has had tuning done if u want to do this be aware that it may and probably will void out the warranty on the car

No u don't however as a gear head I must say its nice to have that much power on tap

8630064X4FORD All due respect, I have seen you posts, and respectfully agree unless you are a trained race driver having 707 HP is a death wish

And I as well agree with you in a street car no there is no need for that much HP, most people don't understand that with high HP comes greater risk and a lot more responsibility, to any one who wants to add more HP they need to take precautions life is not like Hollywood there are no green screens and stunt doubles my advice is to anyone who wants to go fast do it responsible go to ur local track stay off the streets and make sure ur car is sound a lot goes into a car or truck to make it fast and fun. Always do it in a safe manner though

Personally, I don't think a 707HP car should be allowed on the road. Rich kids, that Daddy wants to provide these cars to 'teens' are less interested in the safety of their kids than the show-off element and an inexperienced driver will get themselves killed.

Well put 8630064X4FORD

Yes I agree and thank you fordnut
