2008 250 HPDI SERIES 2 STUTTERING AT TAKEOFF

[DocG]

My 2008 250 HPDI Series 2 stutters almost kicks out after I give it to her on blastoff. It almost is like it is starving for fuel. After Blastoff she runs like a top. If I ease into the throttle almost take 30 seconds to blast off I have no problem.
Any Ideas would be appreciated.

Thanks

I have never...never had to pump the bulb on my HPDI...it starts and runs fine from the first turn of the key. The stuttering is not in my opinion from not pumping the bulb. Not trying to start a war....this is just my experiance and my HPDI has 290 hours on it.

My '08 225 HPDI has been doing the same thing for a year now. Maybe not quite as bad as what you describe but just when the bow is ready to drop you think, its like it loses power for a second or two then comes to. Does it during 90% of takeoffs throughout the day. Runs great on top end.

ALL new fuel filters, TPS adjustment, and new plugs did not fix it. All that changed is my wallet is quite a bit lighter now. Mechanic said no trouble codes stored, fuel pressure looked good etc. I'm at a loss. My gut tells me its something simple but I sure can't find it
