UpRev tune (by Paul @ RS Tuning)

= 301.2 rwhp @ DynoDynamics

P.S.: To the tuner's surprise the car made untuned already 294.6 rwhp, which is why he explained he only managed to extract another 6.6hp.
The AFR was flattened and dialled in at around 12.8 at top end. The exh cam timing was slightly retarded throughout. The tune lasted ~2h and ~20 runs
The random AFR spikes where cause by the jittery sensor in the tailpipe (curve was flat on my dashboard AEM Wideband UEGO)
