I have tuned a bunch of high HP A6's, but I think they were all older models maybe. This 09 will have a perfect graph going on, and hit a brick wall at 680 rwtq. It will shut the fuel off (pressures etc all good) and the car goes 20:1. Same place every time, nearly exactly.
The car had been supercharged for some time, all I did this round was add a few pounds of boost with a pulley drop. The car was about 650 rwhp/tq before for about a year. The car is ran in SD/ MAF off, all the basic TQ tables have been raised, I have done straight percentage drops to both the IFR and VE table equally to see if that would register less TQ, but it didnt make any difference.
Any idea's? the trans tq tables have been maxed also.
thanks for any help
