im thinking of getting a intercoler for my s3 but dont no were to purchase one from that will be good any help appreciated also is it best to get my car re mapped or chipped

 

if you mean flashed or a chip soldered on, it depends of you ecu. The older nonVVT cars have small ecus that can only hold on program so if you want more, you need a chip soldered on. If you have a newer ecu, you have have 3 maps flashed on with no physical chip needed. Performance will be the same, the install is whats only differnt. As for the intercooler, forgemotorsport.com or .co.uk with have what you need.
