Do the chips(resisters) off of e-bay that claim to give your car an extra 15 -20 hp actually work?



Answers:
Not really, what they do is make your engine management system think the car is running cold all the time so what they do is alter the timing slightly and puts more fuel into the system,, basically the car runs quicker and feels more responsive but as for a 20hp gain, doubtful,, worth getting though as it will make a difference
It doesn't work for all cars though, make sure the temp sensor coming from your air intake system only has 2 wires and not 3, coz it wont work if there is 3 wires.
yeh they alter the power curve dictated by the managment system.
They may seem to work for a period of time.They will end up over heating your engine and causing you more cash in repairs.
Yes.Chips can give you an extra horsepower boost. How much depends on the car and the type of chip you put in. The chip will change your fuel dellivery, auto tranny shift points and multiple other criteria to give you the horsepower you are looking for.
yes, but you really need a programer and need to learn how to use it. If you set the car up for highway driving and then go hot rodding, it will be worse. That is the nice thing about the new chips, with a hand held programer, you can reset the power curve to fit how you are driving at that moment. more HP or better fuel mileage. Check out TWO GUYS GARAGE. they always have tips on this.
HI, THE CHIPS YOU GET FOR INCREASING POWER OUTPUT ARE TOTALLY DIFFERENT FROM THE CHEAP RESISTORS ADVERTISED ON EBAY YOU CAN BUY THE RESISTORS AT MAPLINS FOR AROUND 50P
