Is it safe to flash the Stage2+HKSPF 93 Octane LWG map without a turbo back installed? Also does the boost pill have to come out?
I don't think it's safe my friend, you need a turbo back before you run the stage 2 cobb program or you may end up into something in the near future. I don't thnk you want to go that route? Follow the map on cobb or get a tune.
About the pill, you can, so you can get the full power of stage 2 set up, but before you do that make sure you have the right set - up my friend. Check the cobb tunning website everything is there on how to remove it step by step or call COBB
