Porsche 718 GTS Jb4 vs APR Stage 1 Tune Dyno Test Comparison 

Here we go! We have a head to head on 93 octane. Two different tunes on the same vehicle with the same dyno and test conditions. I am just a consumer, and am not affiliated with either company. These opinions are my own, but these numbers do not lie!! LIKE, SUB and ENJOY!
