Just a quick informational post to see how many of you are using advanced injektor pump timing and how it is working out for you in terms of performance, fuel economy and driveability in general.

I haven't found much benefit when delivery starts at anything over 30° BTDC on the 617. I use this setting (along with 4° of camshaft advance) on nearly all of the 617's I tune.

Any input on this subject would be greatly appreciated...Bert
