So I knew I would end up with a box or remap for my car before I ordered it and after a lot of thinking I finally opted for a DTUK CRD-t tuning box. I should say now, it's probably best for all the remap vs box debate chat to stay in this thread: http://www.seatcupra.net/forums/showthread.php?t=390117 so that we can keep this one for those who are thinking of or do opt for one of these and wish to discuss. Anyways, I opted for the box I did because I trust the tech and the company and the output is proven on my engine as they run a mk3 vrs themselves which the box maps were developed on and tested at shark performance. The box and loom is great quality and the instructions are clear and comprehensive: Fitting takes 10 mins tops with both connections on the top of the engine and easy to get to (much easier than the old 140/170). There are logical cable routes and a ready made space for the box between he battery and air box: There are 4 maps which are all documented in the instructions with the shark RR figures. You then have the option of 6 levels of tuning (3+, 3-). I read a lot on the vw and skoda forums about the settings on this engine and the consensus is that 4 + 1 is the sweet spot. I went with 4 + 0 to start with to be safe and all was good, noticeably more pull and still eqully smooth. More noticeable in the first 3 gears. I then switched it to 4 + 1 and sweet jesus this is exactly what I was hoping for! The power delivery is as per stock you just get more of it and quicker - traction is a real issue with 490nm, it will easily lose traction at 30mph in second in the dry when pushed. I'm lucky enough to have access to some private roads at work and I thought a good test would be a 4th gear pull. 40-100 covers the usable rev range and did take 13 seconds, it's now 10 seconds which is pretty impressive. I have lots more to test but initial signs are great. Real world ecconomy is the next big test.
