Whipple 2.9L 2017 GMC Sierra 6.2L...boost and hp limits
#21
Trans set to shfit at 6K. I have HPTuners...with weather and time, haven't had much time to play. Running 3.75 pulley to get back boost lost from freeing up exhaust. Boost on dyno was ~8psi. Haven't installed boost gauge (yet) to see what it is on the street.
