Nice Luis! Happy you were able to get it dyno’d down here. We were at a different dyno yesterday, have to remember our conditions are miserable.. over 100 degrees and 80% humidity.
Looks about right; with the stock turbos, upping boost after a certain point isn't increasing hp by much since they run out of air at the top end, but gobs of torque to be gained at the low/mid ranges. Very nice numbers, esp in that heat and humidity!
