I'm currently running my 2010 wrx at stage one from perrin with a spt CBE i'd like to keep increasing hp so i figured my next steps should be a TMIC and a TBE then stage two. Is that the way to go? I'm new at this modding thing but i'm hooked! PERRIn or PROCESS WEST for TMIC? any suggestions for TBE? WIll that be a major headache everytime i go to the dealer in terms of running my car with a TBE after i reflash back to stock? how soon should i reflash before bringing it in. ANy advice is appreciated thank u.
