Hi everybody,

I have bought a S3 8P about a year ago, been running great, seemed like a stage 1 tune on it (unknown tuner) considering what the previous owner told me. Car was stock with regards to hardware(only cats removed by previous owner), I added the bigger intake from RAM couple months back. Now I decided to do some logging today and see how the trims, and the boost levels are and I can see that the car is overboosting to about 2700 mbar @ 3000RPM. Fuel trims seem to be single digits except when this overboost happens. Also, timing is quite low from what I've read around the forum (it goes down to 0, -1.5 even) so the car is most likely pulling some timing. An aquaintance of mine took a look at the bin file and estimated based on what he saw that he values in there are for a stage2+ tune but I guarantee that the car is not pulling like a stage 2+ car( did a run with a S4 3.0T 333hp stock and even though that car is heavier they ran the same up until 120mph.)

Now the questions:
1. I've been wanting to add a WMI system on the car for a couple months now as the temps around here are quite high in the summer time, not really tune around WMI but just benefit from the added cooling and octane boost overall. Do you guys think that based on the WMI install alone(no software change) the car will get back up to good timing values resulting in a increase in power?
2. Do you think based on the rail pressure deviation that the car will benefit by just calibrating the radius stroke and displacement for an upgraded HPFP, again resulting a increase in power?
3. Why does it overboost that much and is this current tune safe? (this safety thing I must say isn't necessary because I pounded on the car for a year winter and summer, up the mountain and at sea level, and it never let me down once but I just want to know your opinions)

I attached the unmodified log down below but I must say that I missed some logging blocks like requested and actual lambda, IAT temps, and injection timing. I can add those a little bit later once I finish my day job.

All your responses are greatly appreciated and I thank you for taking time and looking through my logs
