If there are 'issues' with the Hellion kit and Lund can tune them ....then that makes him look even better!!
Hellion is not their competition for 2015 Mustangs because Fluid doesn't have a kit yet, ,so there is no competition.
Technically any blower would be competition...is it not always...

It looks home made but I've used one on all my turbo cars, never failed.
I had the AEM Tru Boost.
I received an updated tune from Chris @ BBR and hour ago and there is a huge improvement with the shifting issues!!
It's not 100% yet but it's almost there.
