So it looks like from stock to stage 1 v401 aggressive I only picked up 30whp and 50wtq. I drove the car there with 401 load did a few pulls then uninstalled the cobb and did a stock pull. My powertrain is completely stock minus the secondary cats cut out. It turns out they had a few other 335i dynos in their computer. My baseline was on point with them. 300/320 is nice for now...
