Hypergear Audi S4 turbocharger test and tune

Uploading a short video from one of our high flowed Audi S4 turbochargers. Particular turbo used is our SS-2 profiled option with custom ball bearing center core.

Car is 2018 model, came in with 204awkws on APR stage 1 tune made for the factory turbo. Now pulling 276awkws with WMI on P98 fuel and 255awkws on P98 fuel only. Dyno (CPG) used is very low in reading and factory exhaust has shown restrictions. The owner's more then happy driving off with a 73kws gain, car will come back for more dyno work once aftermarket exhaust system is installed.
