They check out any fault codes on your car to establish if it's good to be tuned. Mine didn't have any so they went straight ahead. Their head office is in Newquay where they have the rolling road facilities and do all the maps, research etc on the rolling road etc, but then they have a mobile van service that visits different parts of the country to carry out remaps at your chosen destination using the map developed for your engine in their head office, that's why there is often a longish wait for home visits- I had to wait a month to get mine done. They won't check your before and after power if you get a home visit, but given the map has been designed for the N20 engine results are likely to be pretty consistent, and besides rolling roads can vary considerably so really not much point getting a rolling road session unless you're looking to see how incremental mods affect your vehicle. Power feels in the range quoted and I'm happy with it, which is all that matters really. Should be there or there abouts, fair few on here with Dyno results around the 280bhp range. If you take to newquay though and get done at their head office I think they will put your car on a Dyno

Do they do any sort of test beforehand to see current figures and if there are problems with the engine, or do they simply rock up, do the software upgrade and go? How do they know what power you end up with, for your particular car (or doesn't it work like that)?
The website says they are in Newquay, I'm North Devon so travelling to them would be reasonable.
