I honestly thought that nothing would happen but my first time driving with it i me and my girlfriend could tell a different is the acceleration and getting to higher speed fast I definitely recommend for a small affordable way to give your car I little something you can feel!!

So I don’t know exactly what this does or how it makes the extra power it claims but I know for sure that my Scion Tc RS 9.0 feels faster and it is changing the way my car runs in some kind of way. When I’m going up a hill in cruise control the car won’t have to down shift like it use to and I feel a solid difference between 40- 100mpbh. The only way I really know it is doing something is by the smell my car now makes under hard acceleration. I have owned my car since new and proper maintenance has been done but about a month after I installed the chip it started running kinda rich and smelling slightly like gas under full throttle. I’m running it with a full air intake system and catback exaust and it’s been a good addition.

Works good but cant really tell

I own a scion FRS. I've had the chip now for about 3 weeks. Although I don't feel in increased any horsepower, I do feel a better throttle response. The mid range dip that this car has is almost gone. I do hope that with a little more time driving the car the chip actually increases horse power, even by if its only 10-15HP.

I feel the power and it does run smoother
