Does anybody have one and did it help richen up 5and 6 so you can cut 1 thru 4 a little more for flow

[W. Tripp]

The PCU does not allow adjustment for fuel flow rate changes between cylinders, just the amount of flow for each load/rpm point.

If you want or need more fuel in holes 5/6 than in 1/2, send your injectors out to be cleaned and flowed. A couple of sets will give you more options. Tony Brucato, Kinsler, RCI and others can do this for you. Used injectors can vary flow by 1-2%(or more) and this can be used to your advantage.

Use the highest flowing injectors in 5/6 and the lowest flowing ones in 1/2. Keep the flow chart and mark which injectors were used for each cylinder. This is all just one step in blueprinting an engine for peak performance.

I hope this helps,

Actually the PCU can compensate for that!

There is adjustment range of +/- 15% for each injector pair right on the PCU.
The RPM and other adjustments affect the entire engine, but knobs marked "Group 2" and "Group 3" allow this differential adjustment for injector pairs 3/4 and 5/6.

We've found this feature of great performance benefit, especially when staggering the runner lengths of the SVS.

Me - not Tony. On the unit I have played with, I completely missed this detail. This makes the PCU a VERY valuable asset to modified engines. Why more rodders and racers do not make more use of this unit amazes me.

The PCU is the easiest and most impressive performance gain we've ever "bolted on." -- although the PCU just kinda "snaps on." Performance, adjustability, plus incredible fuel savings...

win-win-win situation!
