i am puttin on an UR turbo back exhaust this weekend... is there any harm in running a TBE ( catless ) with no reflash or anything?? i hope to get a reflash around christmas so will there be any problem up unitl then??? and if you ask yes i plan on gettin a reflash from you.. what kind of results can i be expecting.... thanks

No but watch for and boost creeps or oscillation aslo dont expect a ton of consistancy but youll be safe
