Aston Martin Vantage Stage 1 tune went in fast and was really easy. Transformed the car. Power is smooth and consistent all the way up. Car is a beast now. Torque hits early and hard and it doesn’t let up. Pulls like a freight train. More importantly. Car feels like it should have been this way from the factory. ECM tune is more responsive, eliminated dead spots and random hiccups in the power band. Car sounds and feels better all around. Even if you’re not looking for all the fun power this is must have tune.

I needed a boost in HP and Torque for my Porsche Cayenne Base model 3.0T Found ECM tuner on Instagram saw the reviews and decided to go with them. Sergej was the tech I dealt with and he suggested a stage 1 tune. I’m very pleased with the outcome. Very responsive compared to what I had. I need to get it Dyno’ed to verify how much of an increase I got. It does feel significant though. Sergej estimates 80Hp 100Torque increase. That’s good enough for me:) $1300 all said and done. I would suggest doing it with ECM if you want more fun out of your driving experience.

Sergey was great. He fit me in his schedule within a few days and had the car back on the road in less than an hour. Completely happy with the Stage 1 tune on my F90 Competition. It definitely woke the car up. I plan to go back for some transmission tuning.

Can't say enough about how great Sergey is. He tuned my F90 M5C and she's an absolute beast. He worked with me on what I wanted out of the tune and the entire process took under an hour, completely remote! If you're on the fence, just do it. You owe it to yourself AND your car to get that thing tuned! Thanks buddy!

I recently had my 2019 BMW F90 M5 tuned by ECM TUNER with their custom E50 blend tune, and the results have been nothing short of spectacular. From start to finish, the experience was top-notch, and the team at ECM demonstrated their expertise and commitment to performance.

Sergey is the best hands down. Excellent knowledge on these "hot v" bmw engines wether it be the n63 or s63, Sergey has the best knowledge and recommendations so that the engine runs safer and cooler. For optimal output, he recommended me run meth injection or a ethanol blend to reduce engine combustion Temps. Also a thicker oil. Do not get a OTS tune and blow your engine, this guy knows his stuff

I reached out to more than 10+ different tuners and no one does American Muscle cars. Serge said he could get the job done and he definitely did. Will be coming back here most definitely. Hospitality 10/10.

To everyone wanting a tune and or even aftermarket part or any short of support. I'd recommend Sergey at ECM Tuner. I've had my BMW 650 X-Drive tuned with ECM Tuner for the past 2 years 70k kms plus without any issues and or hiccups also haven't had any issues when it came down to his tunes and or guidance. Hes always looking to get you the most out of your vehicle while keeping it safe and not crossing limits like most tuners. He's an awesome tech and is always willing to answer questions regardless of the time. His customer service is beyond fantastic and will be doing more business with him in the near future.

I have the stage2 N63 tune and the version 4 cold air intakes by N63 intake. These were installed around 80k miles on my 550i. I now have just over 130k miles. Car is still running strong. Working with Sergey great. The shop I was working with was able to get in touch with him and ask any questions that they needed in regards to the installs. I would highly recommend and I look forward to doing business again in the future.

I recently had the pleasure of getting my car tuned by ECM tuner, and I must say, the experience was absolutely fantastic! From start to finish, ECM Tuner professionalism, expertise, and attention to detail were truly commendable. First and foremost, Sergey was incredibly knowledgeable and passionate about his work(I know he was tired of me and my questions). He took the time to understand my specific requirements and provided valuable insights and recommendations to enhance my car's performance. His expertise in car tuning was evident, and I felt confident that my vehicle was in capable hands. The results were simply outstanding! My car's acceleration, handling, and overall power have significantly improved. Sergey managed to strike the perfect balance between performance and reliability, delivering a tuned car that exceeded my expectations. I highly recommend you using them and only them. You will be extremely satisfied.

I’ve had 3 cars tuned by ECM. First was a 2012 BMW 550i. Second was a 2014 BMW M6, and most recently, a 2019 BMW m5. I’ve never experienced any issues with my cars which were related to the tunes or the aftermarket parts. I’ve also never seen a tuner who answers as fast and is as knowledgable as Sergey. I would recommend tuning with ECM and buying parts from them to anyone!

Definitely a top notch tuner. Hands down one of the best remote tuning experiences that I've ever had and I've owned 48 cars. Don't waste your time on other tuners.
