JB4 Stage 3 testing: 491whp/494ft-lb tq.

jc05e46m3 is no stranger to EAS and was among the first to receive one of the beta JB4 tunes to test with. Shortly after installation (and a few Mexico runs), he returned to the dyno to see what numbers are being putting down.



Runs are maps 0 (off), 1 (mild boost) and 7 (E20 map).







Running Stage 3 configuration on E20 fuel, stock exhaust.
