I was talking to an APR certified dealer the other day and he was saying that with the Stage 1+ program, the upgraded injectors aren't necessary, but are recommended. I dont know if i believe this and i think that it is necessary to upgrade the injectors also. Anyone know if it will work with stock injectors, or will it cause problems and not work correctly?

 

ok, the stage 1+ requires the larger injectors to get the mixture right, in other words the guy is an idiot and yes you need the injectors, its highly recommended

 

Is it worth the money to go with the stage 1+ , can you notice a difference between just stage 1?

 

Yes its worth it, and yes you need the injectors. An FMIC is also reccomended.

 

ahh just skip it all and go bt
