Just wanted to share a bit about my experience with the 5 Star tune for the 2017s. I posted this in another thread but figured it would be worth it to start a new one about it. Hopefully I am the only one with this bad experience with these guys.
FWIW, the 5 Star tune for the 2017s is complete crap. I've been through several iterations of trying to dial down the tune and every tune I get from them is the same.
They can't dial in the transmission shifts. It seems to be slipping during mid throttle. It's awful. I've spent countless hours troubleshooting spark plugs, boost leaks, and checking the transmission mount to make sure it's nothing on my end. The stock tune shifts perfectly but when I flash to any 5Star tune the problem comes back.
I even asked for a tune with stock transmission shifting points. I'm pretty sure they didnt adjust anything and sent me a duplicate tune because the shifting is still just as crappy, the truck started throwing the internal control module torque performance code and I'm getting the catalytic converter inefficient flow codes. The sad thing is that I've been through the process of having them turn those codes off. But when this new tune came in the codes came on again.
On top of this they are horrible at communication. It takes days for them to get back to you or get anything done. After this last go around I emailed them to ask about these new codes I'm throwing. Havent heard back in 4 weeks. I'm sick of dealing with it so I'm done trying to work on the tune with them.
MPT looks like they have a great reputation. I wouldn't touch a 5 Star tune again.
