I am relatively new to Audis although I have been a fan for years and recently acquired a well kept A4 1.8T sport 20V 150 bhp with over a 100k on the clock. I want to increase the bhp and torque and was wondering if it is better to get it chipped or get the existing chip re-mapped and also would changing the exhaust system make any significant difference.
