So…what have I done to my RS5 today?
Well it really started about 7 weeks ago when I decided to use my COVID 19 lockdown time (yes we here are still in hard lockdown!) to replace the front rotors and pads. No issue. Then started on the rears and had an issue winding back the piston. Did everthing by the book. VCDS to retract the EPB, had the audi specific caliper tool but to no avail and yes I tore the dust boot. Knowing my mechnical ability did not extend to pulling the caliper apart I decided to take the car to a trusted mechanic I have used for previous cars. They specialise in exotic Euros and frankly most of the cars there made me feel a little inadequate (a Mclaren parked to the left, AMG GTS parked to the right, 911 Turbo behind etc etc). Nevertheless I was still very proud of my little RS5!
I asked them to repair the dust boot, fit the rear rotors and pads, give the car a once over and while it was there given COVID restrictions and me not in a hurry to get the car back, give me a quote for a new exhaust, an ECU tune and TCU tune. They have tuned a few RS5s with seemingly quite good results (although they kept telling me only modest gains are possible given the NA engine and too much tuning can lead to lots of detonation). I was really keen to go the JHM route for exhaust and tune but the exchange rate and delivery costs and no real local assistance made it just too difficult.
So, 7 weeks later I got my car back today complete with new rotors/pads all round, new upper control arms all round, new front lower control arms, new spark plugs, BMC air filters, Capristo exhaust, ECU and TCU tunes…
They are going to send me copies of the dyno before and after although he said it performed a little under factory specs before they went to work. What he did give me is the attached which seems to show a not too bad HP and torque increase plus a max speed of 246km/h at 8030rpm! Faster than I will ever go that’s for sure.
Given I’m not allowed to really travel more than 5km from home at the moment fair to say I have not really got any great handle on the improvements. He said the exhaust sound will get deeper over the next 1000km or so. It is certainly louder, no discernable drone anywhere, but not obnoxiously loud (which is good). Car feels a little quicker off the line (TCU tune apparently) and perhaps I noticed more mid rev range push but maybe not so much at the top end. Again, very initial small sample of driving.
Next up is PS4S tyres to be fitted in the next day or so and while I had given the car an oil change not long before it went to the mechanic I may change it again.
Other than that I can’t wait to be able to take it for a drive on that long and winding road…
