JDMvtecDRAGSTA

hey everyone,
well i have a problem with my car, at around 5-6k rpm my motor starts to hesitate. it starts shaking and feels like the car wants to cut off on me. it happens when i punch it and when the vtec kicks in.
my setup is:

b16a, jun3 cams, skunk2 gears, 70mm tb, portmatched itr manifold, b&m fpr (50psi), dc jdm 4-1 header, stock block. chipped p28 ericks racing ecu.

i was thinking it could be the fuel but i wouldnt know . the car also sounds really shitty when i start it off a cold start.

help is needed thanks

hmmm, just a shot in the dark...could it be your fuel filter? maybe trying fuel injection cleaner might work?

cold starts with jun 3's and a chipped ecu will always suck

im not sure about your car hesitating check your oil if its low vtec might be stumbling causing the whole motor to stumble/fall on its face

all stock

sounds like ur fuel pump needs an upgrade.
ur running stock 79lph?

I would have to sayfuel too. You got the air flow goin, but whenyu need some fuel, theres none there to mix and your engines gaspin for it.

I would say fuel.. only time my engine does that is when i'm super low on fuel..
