Hi, does anyone have experience of remapping their A4 272 Quattro at all? I have had a box on it from TDI tuning for the last little while, which should be giving around 330bhp and 680nm, but I had the car on the dyno today to check it out and it's only producing 301bhp and 502lb/ft! So was pretty disappointed to be honest, the box is obviously not that reliable. So wanting to remap instead, but some tuners say their remap makes it 320bhp with 750nm for only £299, and others are charging £350 And only quoting 313bhp and 650nm.....So not sure what to go for to be honest. Have had probs with remaps in the past, so want to make sure I get a reliable one done - any advice? Cheers. D.
