Not sure about the mapping side of it, but the only ones i like / have exp of are superchips and REVO so if i cant have superchips then its over to revo, Ill get well lane turbo centre to do it on the rollers, or their is a Revo / superchips dealer in Bradford and they have a rolling road too.
The last time i had my car chipped, well lane did it, they took the map off the car sent it to superchips, they did their thing and sent the new file back to well lane, im not sure if this is the same with hybrid or not.
I really want the S3 lump APY or BAM, mite be cheaper to buy the whole car (seen them go for 3k) and take all the bits i need then sell the rest in bits to make some cash back
