My R8 is a 2012 v10 manual. I sent ecu to VF for the hex tune last month and also added the pop and crack effect.
Car has been acting up after the tune. 1st gear between half and full throttle after 3k rpm the car rock back and forth. It felt like a huge turbo lag and the turbo had been turn on and off on and off as long even my feet is on the throttle very steadily.
Also at 4th or 5th gear gear between half and full throttle over 5k rpm my car started Shaking. I can see the speedometer struggle to go up to 6k rpm as if the car is struggle for fuel.
Dropped off my R8 at Motorwerks houston the day before which is a VF authorized dealer so that vf can diagnose the problem.
Shout out to Travis at Motorwerks and Abe at VF sales department for being on top of the issue.
However the vf tech department has been a little slow in responding.
My guess is the pop and crackle effect is throwing the ecu off on throttle mapping and fuel.
Will keep y’all posted.
