Have people seen MPG increase with 784 injector swap?

I just wanted to see if you guys were getting and MPG increases with the swap or if you just saw response improvement and a smoother idle?

If you did see MPG increase, were there any other factors that may have caused this (i.e. did you not replace the injectors for 150,000 miles and then swap to 784s)?

I tried this a few years ago and saw no difference in mileage or driveability.
I was making a daily 75 mile round trip to work and had hoped for some improvement.
You might see a difference if your stock injectors are dirty.
With the XJ's brick-like aerodynamics, slowing down is your best way of improving your mileage.

They are also the incorrect size for your 2000 and will flow 24# on the rail, enough for a stroker.
