EBL Flash First Time Use

Motor has been together for some time using a custom chip and stock 61# injectors. Just installed EBL Flash for first time and new 74# injectors. K5 Blazer 383ci TBI Sportsman 2 heads Tri-Y headers single exhaust, 2.5" collectors into 3" Y pipe, 3" flowmaster muffler, no cat. Hydraulic roller camshaft, 210 int. 220 exh. @.050, .500 lift with 1.6 roller rockers, 112 lobe separation. Edelbrock TBI intake, 2" enlarged bores. 46mm enlarged throttle body with 1" open plenum spacer. Injector pod spacer, adjustable fuel pressure regulator in factory location. 74# injectors. Factory stock fuel pump set at 10psi (That's all it can do). Fuel pump will be upgraded down the road when time permits. For now I plan to play with the current setup and drive ability of the vehicle. Have completed some VE learns and data log. Idle has improved since first startup but still seems rough. Do any of the experts see anything glaring with my datalog. Just want to make sure I am on the right track.

That fuel pump is DONE. It is already in partial-failure. [Edit] ...or the fuel pump wiring harness has problems supplying power to the electric pump...or the fuel filter is plugged. [/Edit]

You will waste a lot of time, money, effort, and enthusiasm trying to tune an engine supplied by a failing fuel system.

Re: EBL Flash First Time Use

Yeah, 10 would be sub-optimal for a stock 305 with a driveability issue. For your build...it's fuel pump time!
