Had an ad blue fault appear on my works van today with a count down to non start. Contacted the guys at Kernow Sport and they were straight out to me, no down time required, fixed there and then on the job with no delay. Flawless service start to finish. Thanks again gents.

Today I had my VW t5.1 2.0 Transporters egr removed plus a stage 1 remap by Tony, and the results have genuinely exceeded my expectations.
None other than a 5 star review from me.

I wanted a remap on my 2014 Fiat Panda but everywhere I phoned they were reluctant or wasn’t sure but then I found “Kernow Sport” spoke to them and they came out to my house to remap my 4x4 Panda, and I honestly couldn’t be happier. He was really professional, confident and clearly knows his stuff — explained everything as he went and made sure the setup was just right for what I wanted.

He deleted a couple of things and gave it a proper custom remap to improve power and economy, and the difference is amazing. The car drives so much better now — smoother, more responsive, and feels a lot stronger. Even the four-wheel drive system cuts in and out way more smoothly and when it should.

For a small car, it now puts a smile on my face every time I drive it. Kernow Sport have turned my Panda into a Red Panda!

If you’re worried about getting your car remapped I can’t recommend Kernow Sport enough..! great service, really knowledgeable, and all done right on my driveway,
I now have a happy Panda.

Would definitely recommend! Had my Audi A3 Stage 1 remapped and the experience was great from start to finish. Super quick and easy, no waiting around, Tony came out and got it done on the spot. The car drives so much better now, really smooth and responsive. Great service and price too!

After having a DPF fault come up on my Audi a4, I managed to find Tony from kernow sport. I gave him a bell about doing a dpf delete on it. He managed to get me booked in within just a few days. I Took it down in the morning and a few hours later it was all completed along with a performance remap of 200bhp. 100% recommend kernow sport. I will be coming back in the future if needed

100% recommend. Very refreshing to not need to wait to get booked in or be on a waitlist etc, Tony came immediately in person and sorted straight out! Remap was already done by a reputable company on my BMW which had a fault but Tony fixed this as well as making the car drive way better for a great price. Thank you!
