Some of you may know my Mum drives an RS4, the 4.2 V8 420bhp monster. First, according to AmD, most of the RS4's they have on the rollers only produce 380bhp max. Since i got my S3 i have managed to tune it to 375bhp and plenty of torque. So, i went out in my Mums RS4 for the first time after having my car done and i can honestly say it felt slow.... Seemed to take ages to get through the gears and no kick in the chops i was expecting. Whats going through my head is S3 (£27k) + Tuning (5K) = £32k RS4 = £50k Thank god for the K04 2.0TFSI engine!
