Nistune Forums

i have an vl automatic n/a ecu it has a nistune board preloaded with a turbo base map.
i've tried to load on a n/a map car stalls on acceleration i've found out i can only use the turbo maps on this ecu without reflashing, is there any way to temporarily load on an n/a tune until i turbo my car ?

I've attached two files

One for Feature Pack (B490F) and other one standard (B4903) with NA maps loaded

Thank you for your help
