I know some people here have Bluefin on their Edition 30's ..... and 99% seem more than happy.
I'm sure many people by now know of my opinion of SuperChips - just to clarify - I think they are shockingly shyte. And if you go over to Audi-Sport.net, and ask the current S3 owners, they will agree.
And too back up my learned opinion of them, did anyone see Fifth Gear - where SuperChips were specifically asked to provide a map for a VW Polo, for the sole purpose of improving the fuel economy. Dispite the fact that SuperChips should have given it their very best efforts, knowing there would be a large TV audience, they completely FAILED. W@nkers!
Has anyone rolling roaded their car before / after - and what were the results ?
I know what Superchips quote power wise but I am after people who have actually bought it.
Yup, S3 owners on Audi-Sport.net - and the rolling road proved zero gain from the Bluefin!
I have seen numerous Revo examples which show that to be very good - but I am after something I can reflash to totally standard as opposed to Revo's encrypted 'standard' still sitting side by side with their performance map on the ECU.
A couple of crucial points. Revo are seen as the best option - as they
only remap VAG and Porsche cars, and that is where their speciality lies, and they do excel in what they do.
If you go for a SuperChips option, not only do they
LIE in their advertising, they also have no dedicated specialty towards VAG cars. One day they might be attempting to develop a new map for an Edition 30, and the following day, they might be woring on a Kia Pride, or a Lada Riva. I know who I'd trust and recommend!
Onto the nitty-gritty. With the Bluefin, the software physically reflashes your ECU
every time you choose to alter or swap maps. So, yes, you can revert to standard OEM map, but the stealer will know, because, every time you reflash with Bluefin, the engine ECU stores and logs a "count" of the ECU reflashes. When you take it into the stealer, whenever they connect their VAS505* electronic equipment, it can communicte with the "master" database in Wolfsburg, and if there are ANY discrepancies (unexpected, or undisclosed to your dealer) in flash count from your own ECU to those stored on the master database - then bye-bye warranty.
OK, the Revo still reflashes the ECU - but just once. From what I gather, Revo embed both the OEM map and their own custom map on the ecu for their "switchable" versions. Secondly, because Revo have been going for years, and have a considerably high reputation, if the VW or Audi stealer (and Seat and Å koda also) found that you had a Revo, the vast majority know of the high standard of Revo maps, and it would be extremely unlikely that a Revo map would affect the warranty. Obviously, the best approach is to be open and upfront with the stealers, and actually let them know you have a Revo map.
As a final comment on SuperChips - this chap, Clive Atthowe of
http://www.enginetuning.net has years of dedicated, award winning experience of tuning engines, and has a superb reputation. He used to be a SuperChips, and a Revo agent - but kicked SuperChips out some time ago, because of their crap products, and poor technical development. Another interesting link:
http://www.enginetuning.net/New_Revo_software_TSI_AND_TFSI_VAG_.htmlI fancy being able to reflash the ECU as the car is new. If it was outside warranty I would almost certainly go for the Revo with it set to give different power outputs to go with my changes of mood 
Technically, there is NO remap that can be made "invisible" - they can all be detected by the stealer (not the actual content of the map, simply the amount of times the ECU has been reflashed) - so if your new car warranty is a concern to you - then definately do NOT consider Bluefin. Speak to your dealer, and ask if they are OK with Revo remaps!
