Hi. As i'm new to Audi's, the A5 cab we are due to pick up doesn't have the pick up the Megane RS250 had, quite obviously I know. What I'm after is some increase in BHP that it'll be noticeable thru the gears. Does anyone have a diesel tuning box fitted to their 2.0tdi 170bhp that can give it a thumbs up. I take it this engine is a common rail diesel??? I'm very interested in the DTUK offer that is currently on here as they have the CRD-T unit at £359 all in, again, anyone had any experience with DTUK boxes or similar. Mapping is not an option as I want something that is reversible/untraceable. All advice appreciated, cheers.
