Attention: TDR Forum Junkies 
Ok, got a problem. 01 six speed . stage one jammar nozzles ,edge comp box. Holley blue.
Only code is a 1693.
The problem is when i am driving down the road in sixth gear and gradually accellerate from say 55-70mph 2 between 1800 & 1900 rpm i get a very noticable studder. If i turn the edge box off it will still do it, but not nearly as noticeable.
Fuel pressure on the filter housing is at about 13psi. it will drop when you are on it, but never drops below 5psi. Fuel volume is a half a gallon in 9 seconds. The fuel has very little air bubbles, think the size of a pin point, just enough to see.
I have taken the edge box off completly and it still does it.
I have also replaced the apps.
Also last night i dropped the fuel tank , pulled the module out and checked the lines to make sure there was no cracks, where the pump could be sucking air or anything else weird.
The injection pump is not new by any means, but has been replaced about 50k miles ago.
the last thing is that if i am sitting in neutral reving the engine with quick snaps of the pedal - 1k rpm - snap the throttle - let off the throttle at about 1500 rpm- snap it again at 1k rpm ( you get the idea ). if i do that for say 20 snaps of the throttle i will get atleast one snap where the engine bogs or hesitates.
Sorry for the long post , but if you have any suggestions, please let me know. Thanks
