New s6 owner checking in

Hi guys i was recommended this site by the previous owner i bought my 2007 Audi S6 from, i picked it up about 2 weeks go, and im enjoying it so far, coming from a “modified” subaru to this is, its a different breed altogether!

Mods it has:
Milltek non-resonated exhaust(also have the resonated sections for it)
K&N air filters
RS6 front grille( needs s6 badge attached)
RS6 steering wheel
AMI and some other bluetooth stuff for the multimedia
62000 miles on the clock and in pretty good condition in general

I went with my old Subaru buddies to a dyno day for the fun to see how it sounded on full load(niiiiice) and also see what power it was putting down in current condition on Irish fuel(95 ron, probably more like 93 this time of year!) I doubt it could loose nearly a 100 hp since im running it on 95 instead of 97? is there a way to reset the ecu so it re-learns AFR tables etc?

Unfortunately it only made 352 hp and similar torque. Runs were done in 4th gear on a Dynapak. The dyno guys said there must have been some bad electrical interference as there was some spikes on the graph and when he touched the drivers door from the outside he got two bad static shocks which you can see in the video below. So i need some help to try and figure out if there maybe an issue with the car.

The previous owner said he had the engine bore-scoped last year and it was free from carbon build up but it might be worth checking that again.

Is there anything else i should be checking? The spikes you can see on the final run worry me!

I there any data logging software or device i can buy for these cars that would help capture data in realtime? I use Romraider for my Legacy so im hoping there is something similar

Thanks for reading!
