superchipped

Just finished a trip down to Cornwall again and the car de rated its self [at between 3 - 4k rpm] whilst having a tank full of Shell V diesel - anyone else had this problem?? Filled up on the return jorney whith "stadard diesel plus double dose of millers" and no proplems with derating??!??

I bought an FR yesterday that had already been superchipped. The car drives well and has plenty of poke. It doesn't actually feel that fast over my old tdi sport, but I think thats down to it being a lot smoother than the Mk3. The only complaint is the torque in bigger gears lower down...

As simple as the title, tell me gentlemen (and ladies) i took a little trip into Seditas Cars in Ayr which specialise in turbo tuning to have a talk about my engine modifying options and i was told that superchipping would be better than revo'ing it for performance and such like? What does...
