Ireland 29th Apr 10 Jaguar x type 2.0 diesel 130 bhp. I bought a red power tuning box last month from yourselves,The transaction couldnt have been easier and it arrived in Dublin a few days later. The fitting instructions inside were perfectly clear and the product and packaging all looked of excellent quality. 10 mins to fit..easy.It came with 15 settings and was on setting no.7. Drove the car at this and although it was smoother i didnt notice any real difference in power. Onto setting 8. Straight away pulling out of my street the car was a lot more lively and the turbo more defined at 2 thou revs. i have it on setting 10 now and it makes power from earlier than 2 thou and until a lot later in the rev range. I unplugged the power box at the side of the road to go back to standard and its now that you can really appreciate the difference the unit is giving.I havent been able to see any improvements in fuel economy yet mainly because of planting the right foot a bit but the car doesnt seem any heavier on diesel.. Great product Thanks
