I just bought an 03 WRX and found that in it was installed a GReddy Profec BSpec-2 Boost Controller (I think?). I'd like to remove (and maybe even sell) it - can anyone give me any help or advice on what to do?
Has the engine been modified during the installation of this device? Will I do damage or will the engine be inoperable if I remove it? Am I better off just leaving it connected and not using it? Can I do this myself or do I need a professional to do it?
To whoever can help, thanks!
