2 cars with the same OS have flare. 2 other cars with a different OS have no flare at all. All the cars are Magnacharged.
I have found with A6 cars that if the reported load of the engine is not "spot on" you can get flare issues. Since the T43 is a torque based controller if the MAF and VE are not dialed in (which is reporting load) the trans will calculate at a lower or higher load then is correct.
We have been updating the OS with a MDI box but have also found the Mongoose Pass Thru cable is still working....much to popular belief...the 2010-2011 Camaro still uses 2009 logic as the car was released 1.5 years late and uses the early stuff.
