I was talking to my mechanic and he said he recently did a fuel injection upgrade to an xb9sx with a K&N air filter and modified the standard exhaust to increase the airflow but maintain the original look. In his opinion it runs better then he has ever had an xb9 run before. Has anyone done an upgrade like this before? Or have any recommendations on the best combination when upgrading.
I also talked to him about an ECM upgrade to a race ECM, apparently the race ECM has been outlawed, is this true?
