UK-POLOS.NET - THE VW Polo Forum

Hi im pretty new to the forum and car modding in general, i have a 2013 rline 105bhp which i have lowered, added a performance filter and back box delete, ive also blocked the gap in the grill intake so air flows straight into the turbo rather than the engine bay. I was wondering what engine upgrades help add some performance for when i get it mapped, im talking about the small things like spark plugs and ignition leads! im also wondering if anyone has bothered with the forge blow off valve and if it is worth the money.

Thanks
