    Chef’s Kiss

    Posted by Stella & Nicole on Dec 12th 2021

    I’ve been with Michael ever since I purchased the car early 2020. We started at the bottom and now my baby shoots flames. (We really did ‘start from the bottom, now we here’) I’ve always kept in contact with any issue my car has had. It has never been an issue with the tune or tuner, it’s an n54, there are going to be problems that arise when you’re pushing your car to the limit that are out of anyones control. I send logs (religiously) and he always gets back in a timely manner. Example: I went to Maggie Valley for a show and told him I wanted to stand out the day of the show and BOOM he sends a tune with a ghost cam. Mission accomplished. I have absolutely nothing to complain about when it comes to his magic tunes and my 335i.

    Upgraded Turbo + Meth Tune

    Posted by Corey McKeigan on Dec 12th 2021

    I have worked with Michael starting all the way back to a custom tune for my stock turbo car. The car ran extremely well but I wanted more. Michael was there to give build advice on top of tuning my car. I make 600awhp/600wtq on a tune that is more than safe with my fuel setup. Great guy to work with.

    Micheal is awesome. He can tune your car and get it running at its best and safely. He doesn't take chances on your engine like some tuners. He is also a super knowledgable n54 guy and I ask him about my car before anyone else. He has been nothing but a great help to me during my build. Even though I took my car off the road for a few months, I'm ready to get back at it. And have Micheal finish my tune. I ve had several n54 tuners in the past and Michael Hollingsworth is my favorite so far. Do not hesitate to drop him a line. He will set you up
