Snake Oil!
The EX has 276hp and 248ft lbs torque!! That’s more hp than my 8 cyl F150 @ 205hp.
(Slightly less torque though the f150 has 275ft. lbs)
Why risk damaging the vehicle or at minimum loose precious gas mileage using an ECU chip?
I tried this with my civic and it gave me a few extra hp which did not help my clutch or gas mileage. In fact It dropped about 10mpg adding that thing. In the end I ended up putting the car to its original settings. The horrible fuel economy wasn’t worth it to me.
Snake oil. It it were that easy, Kia would have already done it. You seriously think that the Sorento could get 50 MPG with this thing?
If that technology were available, Kia would be selling more Sorentos than they could possibly build if they could get 50MPG with the addition of a $6 part.
Seriously, I'm surprised eBay lets people sell blatant scams like that.
