2 questions

1> just wondering if i can run 42# injectors on a non tuned car , that has full exhaust , 3" intake

2> i have a spare computer with supposly a STAGE 2 flash on it that needs to be relearned to my car , if i take it to the dealer and get it flashed to my car is there a way they can tell me that the tune is actually on there?

 

1. no
2. I think so

 

Okay thanks , another thing should I change the injectors before goin to dealer to get the PCM flashed to my car or change them after they do it ? And would I have to change the pulley right away aswell

 

You need injector change WHEN they do it.

Pulley doesnt matter.
