i have a 2001 xj and im just tryin to get better performance out of it. i seen a thread on 784 injectors... how are they compared to stock injectors?

 

I am not an expert but, I have been reading some of the threads for future upgrades on my 2000. As best as I could tell from various threads, the 784s will likely gain us a better throttle response and potential mpg gains. If you have improved intake and exhaust some power gains are likely.

The 789s may be slightly superior according to some.
