Very professional friendly staff. Excellent power addition to a frustratingly slow vito van.Mapping can be a scary world so I would highly recommend these guys.

A fast and efficient service. Easy to book by phone and arrange to have this done at a convenient location. Telephone update on the day to let me know Jonathan was on his way.
Such a pleasant employee and an attribute to the company. Definitely delighted with Performance Ni.

Quick and easy with the team! Less than 24 hours later I was driving out with my stage 1 remap after contacting them! Professional guys would highly recommend! Car is an absolute dream

Went in to get a stage 1 remap and get/dpf delete, very happy with the result and it was done in 30 minutes, would recommend this business to everyone

Really pleased. I got my van tuned in my driveway at a time that suited me.

Fantastic service. Like driving a different van with no restrictions and massive difference in performance and power. Would highly recommend.

Excellent service from start to finish! The team was professional, knowledgeable, and passionate about what they do. They took the time to explain everything clearly and delivered fantastic results. The quality of the work and attention to detail were impressive, and the whole experience was smooth and hassle-free. I would highly recommend them to anyone looking for reliable performance tuning in Northern Ireland. I’ll definitely be back in the future!

Professional service and noticeable difference in the car.

I’ve had two cars now done by Mark & his team, both times using the mobile service which is so convenient as both remaps where done while I was in work meaning I lost no time in travelling into Belfast.
The gains are unbelievable & have unleashed the true potential on my 2022 Audi A5 increasing the bhp 40% & torque over 30%
Cheers lads 👍

First class work, fast and efficient, many thanks.
