    • GIAC releases Stage I B8 S4 3.0 TFSI supecharged V6 software - Gains 98 all wheel horsepower on 91 octane

      GIAC finally has shown their ecu software for the B8 S4 with the 3.0 TFSI supercharged V6. The car was dyno'd on 91 octane with nothing else but an AWE intake. The gains are amazingly almost 100 wheel horsepower. We can not explain how GIAC was able to do this on 91 pump gas considering APR is getting about 64 all wheel horsepower with their software. APR hit a peak of 361 wheel horsepower on 93 octane with an exhaust on a Mustang dyno. GIAC hits 404 wheel horsepower with their software and an intake on 91 octane. Hard to believe but if independent results verify this, wow.

      The car in question is a 6 speed manual which may account for some of the increased gain versus APR if that S4 was a dual clutch.

        Meh. Never believed their numbers. Ask even @Ryan Mills He had the first AWE/ Giac k04 upgrade for his TSI and they claimed like 300+ whp etc on the dyno just like this. He was barely hitting 260 whp.

        They manipulate or something. If not, good for them that's a good increase in power esp for a SC set up.

        If they in fact are showing inflated figures I do not think any of us will allow them to forget it or live it down. I look forward to seeing more results as these are hard to believe.

        If true, F!!!!!!!

        but you can see the curves a little inconsistent from run to run so either these are glory runs or more suited for 100oct file.
