2020 GT Indigo———I installed a brake snip switch to be able to launch with more boost. Now when the switch is off, the auto off light flashes and car goes into limp mode. I have tried disconnecting battery to reset everything but every time I try to use it, it does the same thing. Please help. Thanks!

You might try checking or removing the switch. That might be the problem.

Tried removing switch all together and same thing. Also replaced switch. Same thing. Is there something I am missing with this brake snip mod?

Green wire black stripe? spot #83 on the connector. Maybe an ECU reset?
Open the hood, lock the car and put the fob away from the car. Wait 5-10 minutes. Open the hood and disconnect the two ecu connectors. Wait 30 minutes and then reconnect. Then restart the car. It might work.

Tried the ecu reset. Same thing. I don’t know how to upload pics to here from my iPhone. Sorry.
 
First, if your cruising around with this flipped you're already making a mistake. If you're saying the A is flashing, then you put it in beast mode. That only happens several minutes after you flip it, sitting in Drive, with the foot on the brake. By limp mode, I'm assuming you're trying a launch, the car is taking off and then falling on it's face? Yup, that's beast mode..... Unless you have an ECU flash or an aftermarket ECU, the nany takes over to protect itself.
Wait until your ready to stage or do your launch, flip your switch then... you have plenty of time. Don't necessarily need to floor it either. Slowly press the gas, when you're at about 1/2 pedal, you will see the boost start to climb from 0.00 to xx. x meaning number start to build pretty quick. At that time, finish smashing the gas and let up the brake. The car should hold it no problem.
