I'll report back in a couple of weeks when I've done a couple of tanks. I have used these quite a bit though and always find a real world improvement. This original post was backed by the fuel I'd put in that day (not necessarily just the OBC).

Stan, I know youve mentioned your remap before and it sounds like its reset or something?? I've never experienced that with a box, the power difference is very noticeable and worth it for that alone. My Previous RR's!

+1 For how they work. I run one they do seem to offer some improvement in mpg and power but also noise IMHO.
Turbo diesels seem to gain the most from them. My current one is adjustable and I am not 100% convinced by it. my previous one on a different car was fixed and I was impressed. When I sold the unit on the buyer was also very pleased. It would be good to compare the advantage but as mpg is so subjective depending on car and driver.
I can get around 30-31 average at 70 running a box, K&N and no egr. 23 normal average on mainly short runs and about 26 on a cross country run. Mine was a blue one!
