looking for a bit more poke and better drive from our 1999 v plate a6 . would like more power and better response. not sure what to fit on it(chip/zost/springs etc) .. i import jap performance cars and parts (mostly subaru imprezas and legacy's) for a living so i know all about tuning stuff for them but like the refinement/luxury and civilised drive from this car . any suggestions/info on whether its remappable/chippable etc would be nice and also what exhaust to fit for a nice growl but not chav loud... would like to retain ride quality but lower it a little too so interested in shorter springs that can be used on std shocks or a lowering kit that aint too hard . so as before, any suggestions would be gratefully recieved....obviously costs are an issue and dont want to throw thousands at it . thanks in advance , rab.
