It could very well be the combination of your chip and timing. When I last called ADS, they said I had to run 93 octane and stock timing which is 10 degrees BTDC. I'm sure Hypertech will say the same thing. Try the gas first and then verify the timing. Other than that I'd say you could be going lean, but we'll look into that after the gas & timing check.
