i have a silver bugeye with all the normal mods and an ecutek map. i had the map done with the dump valve in 50/50 mode. can i change to full vta or even full recirc or will the map not like it. dont know much about these things so any help appreciated

 

It won't matter, as the dump valve will be fully closed when on boost regardless of which mode it's running. 50/50 is probably the best mode so I would be tempted to leave it, or you could run into idling/stalling issues.
