Hi all,
I have been trying to chase down an issue with my tune but I don't see a reason for whats happening. Mods are Rotofab intake w/ dry filter, ported OEM Intake Manifold and Throttle Body, Full Borla exhaust with secondary cat delete. Car drives perfect except for at full throttle as soon as it shifts into 5th gear. I can feel the lack of power from 4th gear into 5th (A8 Transmission) but then after a moment the car picks back up again and the full power is back on. You can see in the attached screenshot that timing is way off (15 degrees) when this happens but then it returns to normal (23ish). Has anyone ever encountered this? I've left my Virtual Torque and Virtual VE stock for now. I was going to adjust them in only the problem area but I'm just searching for more info before I just start changing things.
Tune, Datalog, and screen shot attached. Any knowledge is welcome. Thanks!
