Car has ran fine up until a few days ago. It has started to bog, cut out, buck under heavy throttle. Can drive fine up to speed in city and highway but as soon as I give it throttle to pass or accelerate hard it does its thing.

Specs.
b18c1/b16a head
skunk2 intake
Skunk2 tb
rc 550 injectors
buddy club spec IV cams w/ matching cam gears
supertech valve train
12:9 supertech pistons w/eagle rods and eagle crank

Things I've checked/changed.
distributor
injectors
ecu
plugs
wires
iacv
map
tps
grounds
main fuel relay
new fuse box
bled the coolant system
compression checked good on all 4
no codes thrown.

I'm sure it's something simple, I'm just stumped. Any help would greatly be appreciated.

 

i sure all sensors are receiving proper voltage, and fuel system stays at pressure when pushing the gas, your injectors might be squirting gas and not spraying when they completely open

 

I will be checking to see what fuel pressure is while driving tomorrow.

 

Cutting out under load is almost always a spark issue. If you only "checked" the wires.....change them.

 

air filter......... seriously... the most over looked thing lol
