Hi guys , I have a 1998 t4 s40, has a forge dump valve on but I want more power and my engine light is on due to lambda sensor and camshaft sensor. I've owned the same car previously and it's been in my family for 12years previous to my ownership, any advice on a remap with good figures and the direction I should go for achieving 270ish bhp level? Any help is much appreciated, I love my drifting but I can't help but not love the s40 T4 😁
