I have an 03 v10 with a Powerdyne supercharger. The Ex came with an extra computer with a Superchip. The Superchip has a proper tune for the supercharger but when I install it with the extra "bad" computer the truck will completely shut down after driving ~100 miles. This is very dangerous because I lose power steering and brakes during the shutdown. The Ex starts back up after a few minutes and then shuts down more frequently until I reset the computer. I speculate that something is going wrong after the "bad" computer has learned the driving habits. The other "good" computer works great and does not ever shut off the motor, but at full throttle the Ex will bog and I am losing HP produced by the SC. I don't think it has the optimal tune because my wideband AFR reads lean right before it bogs and I think it is bogging to protect the motor from a lean condition. I would like to install the chip into the "good" computer that never shuts the truck down to get the benefit of the proper tune, but I don't want to risk damaging it or experiencing the dreaded shutdown. A few questions I would like everyone to advise on:

Any idea why the truck shuts down while under power?

Any reason to think that the chip will cause the "good" computer to shut down while driving?

Could the chip be causing the shutdown, not the actual "bad" computer itself?

Would the best option be to send the chip to 5star tunes and have them program a tuner with the superchip tune...and a few others?

Any way to flash the "good" computer with the superchip tune?

Other ideas?

 

Personally, I would get on the phone with Mike over at 5Star. I bet he would have some ideas.
