Given the heat, altitude, and fairly conservative tune you are running it doesn't sound too far off. My guess is a stock M3 would be down an additional 20-30whp.
Definetly true, when I had my 335i i got the JB4 for it and then dynoed it back in Tucson at elevation in the heat and it put down around 35 horsepower less then all the cars that dynoes at sea level with mild temperatures, not to go into details but one was same dyno and same lack of mods.

Also whenever I drove down to California/Oregon/Washington the car felt way faster, but I am not sure how the Boosted/NA compares to diffrent climate and elevation changes.
