Please can someone quantify for me how the MPG changes after a Jabba remap on the Fabia vRS?

I drive a lot of miles so it's an important consideration for me.

Mine has been Revo'd - the mpg improved by 1-2 mpg with NORMAL driving

Trouble is you tend to cane it for the first couple of weeks after chipping, so the MPG suffers a bit

Not much change if you drive the same, which is very hard to do, then there is a slight improvement! But wheres the fun in that!!!!
