So I have never invested in a proper detailing service before however the phantom black paint on my used S4 was showing plenty of swirling and general neglect, so I decided in warranted a bit of correction and care from someone more versed in such topcis than I. Got to say Lee at LNS in Farnham did a top job. Surface is like glass and upon collection had optical clarity to match! Delighted with teh detail I then took it over for a quikc power run on the dyno to check what the APR remap was giving me. Have to say pleased with the results given this is 95 grade fuel (company pays for it and get's upset if I buy the good stuff). APR remap, pulley upgrade and a pipercross filter are only upgrades. Stock reached around 348, map activated 424. So the lower line is the stock mapping and the upper lines are with the APR 95 map and fuelling.
