We are still investigating the "jerkiness" experienced by a select few owners on their cars. We have had several vehicles come into our facility for testing and we have not really been able to replicate the issues at hand in-house. Some cars that exhibited this issue did have some boost leaks on the cars. Right now, the v203 maps help this issue and seem to remedy it for now. There will be a new series of maps released in the coming future. There is no current ETA. Thanks!!
