I have a 90 passat and i was wondering what kind of cheap mods i can do to increas the performance i already have a muffler
1.You can use a chip mod for the ECU 2.You can buy a bigger tires and wheels 3.You can tune you o2 sensor to give a better fuel mixture 4 The easiest way is to put some low air turbine
where would i find a chip and how much would it run me
There are different types of chips try to find them on Internet .and read the description .But they should be not expensive
the chip is about as cheap as it is going to get though.anything less really isnt going to do anything except tires and wheels
