2nd May 14 Hi Andy Just wanted to say thank you for your excellent advice/service on the FSR tuning box for my S4 3.0TFSI. After the box arrived less than 24 hours after I ordered it I couldn’t wait to fit it. I was absolutely amazed at the increase in power the box made to the car. The car went well prior to fitting the box but is now just something else. I am currently running Map 4 +3 and the car hasn’t missed a beat. As you know I was a bit sceptical at first about fitting the box as I have always gone down the remap route. But after experiencing the difference the FSR made and the fact that it is so easy to fit and is not traceable once removed, I would recommend this product to anyone. The best money I’ve ever spent. Why anyone would want to spend £1000 +VAT on a Revo when you can spend £500 on the FSR and make it go like a guided missile is beyond me. Going to get it Dyno’d ASAP so will let you know what its pulling. Thanks again for all your help Dave Sent from my iPhone
