Installed inj, 2 cylinders failing contribution test.
I just installed 238/100's in my sig truck.
At the same time I installed valve springs, push rods, and head studs.
Truck started easily, after about 4- 15 second cranks with a minute inbetween.
All injectors pass the buzz test,
But #1 and #6 fail the contribution test.
It runs like crap, as expected after an injector change, but even after putting about 30 miles on it,
it is still running rough and showing cylinder #1 and #6 failing the contribution test.
They are new rebuilds from rosewood.
TS chip is from beans, tuned for 238's.
I'm getting 2700ish psi ICP
at around 40% duty cycle.
The chip was tuned for use with an adrenaline, which I haven't installed yet, but I can't see that being the cause. The stock 15* pump would hit 3000psi+ with my stock injectors.
I guess I'll start by pulling the #1 and #6 injectors, but I'm not sure what the problem would be here.
