I initially put this in the turbo thread, but am posting over here because I am thinking it is a tuner issue.

I had a turbo installed by Trask a few days ago. They use the Thundermax.

Prior to turbo install I had pipes, air filter and Powervision tuner. Ran it hard, no issues.

After turbo install, If I twist throttle 70-80 % it runs hard. However, when I am at Wide Open Throttle, there is an issue.

Starting in 2nd, redline it, go to 3rd, redline it, shift to 4th. at WOT in 4th, there is a loud backfire and the bike shuts down. Here is the weird thing. I can turn the ignition off and it does not turn infotainment, lights or gauges off. I need to turn it off and on like 3 or 4 times then it will finally turn all of that stuff off. Bike needs to sit for 5-15 minutes and then it will start and run fine again.

Trask initially told me it was the system relay. Changed that. Same symptom. Now they are telling me they think there is a wiring issue with my amp. I call BS because it never did that prior to the trask install. I ran it through the gears with a few buddies prior to the trask install and this issue did not happen.

I am thinking it is something with the Thundermax. I told trask I am not going to chase an amp wiring issue until they work with me. They will be back in the office from Sturgis on Wednesday and they are going to work with me. Does it seem like there could be an issue with the thundermax?

Thanks for the input.

Bike is a 2016 Road Glide. Stock 103.

 

FWIW, it was a Thundermax issue. They had me update the firmware and it resolved the issue.
