Some random thoughts on this...

Since the Trinity has a setting to put it into "sleep mode", I'd suspect there's something more going on with the ODBII port, especially on the LX vehicles. I had a 2008 Charger Daytona that did EXACTLY the same thing with AeroForce Scan Gauges. Dead battery every ...

The two runs that overlay are the stock tune and the Predator 93 CAI tune. Brent at Dyno-Tuned Performance had the same reaction and checked the Predator to make certain it had installed the tune.
The black run is the Custom tune they installed.

I don't have the specific A/F info in front of me ...

I dyno'd my '09 Dodge Charger SRT8 today.

Max HP stock was about 360 (Red). Torque was about 370 lb-ft.

Results with 93 Octane CAI Predator were nearly identical (Green). Modest gains (1-2 hp) in the low end, but max HP was still 360.

We noticed the Predator was making the A/F ratio even richer ...

Just downloaded and installed the 93 CAI Performance Tune. Will test tomorrow.

Can I assume everything in this discussion about updates for the Challenger will apply to the '09 Chargers too (except the 6-speed stuff)?
