In Germany the race chip is known as 'Russ Chip' (soot chip) and even AC/DC wrote a bunch of songs about it (Let There Be Smoke, If You Want Smoke You Got It, For Those About To Smoke We Salute You...)
Up to 90hp is tempting.
Couple of months ago I was about to buy one but refused after reading too much about rough idle, clogged DPF, CBU, wavy torque with cutout above 3500rpm
