Back in the day, while running Hahn stage II, I put my car on a dyno and the afr spiked to 14+ and the tuner shut the engine down for fear of blowing he engine. We had to back the boost off to around 6.5lbs to get the afr in safe range (around 12/1).

At 15-17 afr shouldn't the car detonate much more than it did before?
