Xero Limit

Mike has always done great things for my FRS, pretty much built it from scratch, from the custom built motor, to the edelbrock supercharger, to my race seats, to my custom X brace roll cage, everything was quality. Super knowledgeable guy and spends the right amount of time to get the car to perfection. Would recommend Mike 100%.

Mike tuned my Toyota on his dyno and the power curve was amazing. After more modifications he e-tuned my car. MIke is anazing tuner and incredibly professional. If you have an EcuTek kit and need your whip tuned I highly recommend him.

Wow, what a difference! I switched to Xero Limit for the EcuTek tune on my Supercharged Miata NC after being very disappointed with another tuner and am so happy I did! Mike is quick to reply, had an incredible turnaround time and got my car tuned in half as many tunes as the other guy (who took forever and made me feel like an idiot that was bothering him when I needed help). The car runs better than ever and I am incredibly happy! Highly recommended!

Update a few years later. I called and sent email looking for advice to get the car they tuned to pass emissions, they refused to reply. Nothing. I’m not so pleased anymore, what I liked previously was how easy it was to talk with them, maybe they’re too big now and don’t give customer service like they used to. I was disappointed so I updated the review.

Purchased a Flex fuel kit for my FI build. Mike took care of the tuning on my 13-FRS He worked with me until it was perfect, he was responsive and flexible and ensured it was completed correctly A+

Mike transformed my car from a boring, stock machine off the dealer lot to a street-legal race car. I'm very impressed especially for the price, he offers a great value. I highly recommend Xero Limit to anyone looking for a performance boost and great customer service.

Mike @xerolimit is by far one of THE best NC Mazda MX-5 tuners around. Tuned my turbo build exactly how I wanted it. 5-6 email log n tunes and Mike had my car running fantastically! Professional. Reliable. Top Quality.

10/10 would do business again!

Mike is a real stand up and patient guy. I had gotten my supercharger installed and everyone highly recommended me to him. From a year of my poor installation issues, he was patient with me gave me alot of attention needed to get my car the best and as reliable that It can be. If I were to add any modifications that need tuning, I would 100% go to him.

Mike is extremely knowledgeable and professional. He tuned my FRS when it had a full exhaust and intake several years ago, then just last year tuned it again after having my jdl kit installed. The car has been more reliable then my stock daily. If you're looking for an experienced shop that you can depend on, look no further.

I've been a customer of Mike with my BRZ for almost 5 years now. Very professional and knowledgeable about what he does. My car has run flawlessly over the years while being tuned naturally aspirated and tuned with a jackson racing supercharger since 2017. Would highly recommend going to Xero limit.

Xero Limit products are top-notch! I have their intake and cams, and also purchased other products. Mike is great to work with - timely with communication and service - and his tunes are helping me produce incredible power! I proudly run Xero Limit decals on my car because I believe in the business!

I have been hearing great things about Mike for so many years and finally got a chance to work with him on tuning my car. Of all the forums and reviews I have ever read, I have yet to see these guys get a bad rep/review. One of the best shops on the whole east coast. He is fantastic to work with and I plan to do plenty of future car work with him. He tuned my 2018 Subaru BRZ and did an amazing job. After the first logs and tune that he sent, it already felt like another little beast, considering it has lower power to begin with. Xero also has great prices on their EcuTek and tuning package among other parts. He is just an all around easy and very knowledgeable guy to work with. Knows what he is doing without a doubt! I look forward to getting some more revisions on my tunes done when I get a few other parts on, as well as some dyno tuning in the near future. Highly recommend!!! Thanks again, Mike!

Bought a flex-fuel kit, ecutek hardware, and tune from Mike at Xero Limit. My experience has been great so far. Any issues have been addressed promptly and professionally. I'm happy with both product and service. This is the shop formerly known as Moto-East and it's a go-to for many on the 86 platform.

I would recommend Xero Limit. They did a tune for my 2007 MX-5 a couple of years ago (under a previous company name) and just did an update to that for me. My experience has been quality work with good responsiveness and turn-around.

Mike is extremely professional and will do everything he can do to meet your needs. Your car is guaranteed to run and perform better with Mike handling it than with anyone else.

I had mike tune my mx5 quite a few times in the past when I either had to do emissions, or had a ecu get bricked by some water. He was always very kind, very fast, and very VERY good at what he does. I would reccomend him to ANYONE who wants any kind of ecutek tune for an NC mx5. If I could rate him 10/5 I would.

Having worked for Mike he is an extremely knowledgeable and fair individual in the performance automotive industry. I would definitely recommend his business for any aftermarket performance needs.

We do all of our remote tuning through XL and always have quick turnaround with great customer service. We also buy lots of parts through XL including cams.

Mike's always been very knowledgeable and patient with my questions and concerns. Has helped my car come a long way since 2014. Great pricing on parts and labor!

Mike went above and beyond to get the tune right on my 2.5 swapped MX-5 and his service is the best!

Mike’s a fantastic tuner for the 86 platform. Easy to work and the cars a night/day difference compared to a stock tune
