Skoda Octavia 2.0 TSI Vrs 226 bhp Petrol

Posted on 20th September 2020, 21:46

Hi, I drove to Celtic Tuning HQ a few weeks ago to have my VRS remapped. My car is actually the 242hp version with the 7-speed DSG. I was very impressed with the greeting I received and all the information I received about the potential I gains I could expect. I went for a walk into Newquay whilst the remap was done and then it went on the rolling road. The car was ready on time and they suggested I took the car for a spin before I drove home and I was amazed at the torque and bhp gains. It drives like a totally different car and the way it should feel and handle!!! I was happy with the performance of the car before the remap but now I'm over the moon with it!!I would recommend Celtic Tuning to anyone looking to having their car remapped. They are very professional and will answer any questions asked. I am over the moon with my car now and have saved myself many thousands of pounds on buying a car like a Golf R with a similar bhp. I am pleased that they have a rolling road as it proved the bhp and torque gains I now have and that is a huge plus on other companies who don't have rolling roads and who claim the gains you have without being able to prove it! This also enables Celtic Tuning to tweak the remaps to the exact setup of your car!!!! I will definitely be using Celtic Tuning again when I change the car in the future. But that may be many years away as I'm so pleased with the job that they have done and how they have transformed my VRS!!!

Dear all,

Just wanted to make the time to say a big thanks for sorting out my VRS yesterday.

Finding out that someone had already re-mapped it wasn’t that much of a surprise but I was worried about the software that had been uploaded.

The drive back to Bath was much more “enjoyable” for 2 reasons:

1) I had the peace of mind knowing that your software was now in the system.

2) The ‘smoothness’ on the uptake of the turbo just made it so much more fun.

So, once again.....many thanks.

Great value product that really unlocked the potential of the engine, Alot more power through all the gears and about 3-4 more mpg.

Cameron, the technician, was professional and friendly. And I liked that the van was so clean.

Definitely recommend.

Having previously had my Octavia VRS re-mapped, I waited all of a week to have my Superb 4X4 done! Arriving at a slightly unfamiliar location made me realise that Celtic had moved location, now in a comfortable, well appointed building their service had unbelievably got better! Sitting in comfort while my car was dealt with, watching on a large screen monitor what they were doing was good.

When the moment came to test drive the car after they had performed their 'magic' it was a revelation - smooth delivery of power from low down - pulling hard right up the rev range. I knew I was going to get this on my way down - yet it still comes as a surprise when you drive it.

Three months on and I can report long term improvements, aside from the increase in BHP to nearly 200 from the previous 138, fuel consumption (all important to a tight-wad like me!) has improved beyond my wildest hopes. I had seen about 8% overall increase with the Octavia VRS, but with the Superb 4X4 - I am now seeing 57MPG+ on my regular run to south Wales! Which equates to an improvement of about 14% - STUNNING!!

I can only say a big 'Thank-you' to all the crew, and having the power curve printout from the 'works' makes it worth the trip down! If you are thinking about doing this to your car, get it booked in!!
