Injectors installed, a few new symptoms

[csdwarf11]

Hey guys, got my injectors in last night and probably have about 25 miles on them. I know It will be around 200 miles before everything seems correct again, but I have a few questions


First, it was pretty cold out last night and this morning, but my truck is failing to warm up, gauge stays way down low, and the actual engine is not very warm to the touch. Im thinking leaving the truck in the shop, not running and with no coolent for 2 weeks that maybe the thermostat stuck?

Second is, the truck seems to operate fine...but it has well, a lot less low end torque then it did before, I have to be much more genital on the clutch to take off, and you can hear the engine strain more then it used to.

Third, Im assuming its because I have air in my HPOP, but I dont seem to have much more power then I did before, if any more. Also a sign I noticed is on NONE of my tunes do I have even a HINT of smoke coming out of the exhaust. I'm glad I dont have any smoke, but it seems like a sign that I might not be getting much fuel. Because honestly, A stage 2 truck with a stock turbo should smoke some I would think.


Also, EGT's are very low, I would expect to have to keep my eye on my egts' but I can WOT 4th gear on the high way and boot levels and EGT's stay in check no problem.

Air in the HPOP system? not building enough pressure to support more fuel yet? No codes though

I've never needed more that 20-30 miles to get a inj swap to run correctly...

Something wrong as with a stock turbo it should smoke like a freight train and boost very fast.

Thats what I figured, Im not getting fuel from the injectors like I should.

Any ideas? could it be the tuner isnt working correctly? because the truck seems to run alright, just not much fuel.

My old canned tunes on my 6 pos smoked more then this. Lol

I have no idea what going on lol. Truck seems to run completely fine, except like I said noticeable less low end torque off idle and the idle might be a little rougher (not much, its pretty good)

Edit-Dont get the idea im trying to get smoke, Im just using it as an indicator that im not getting nearly the fuel I should

Good fuel pressure, hpo I dont have a gauge on...but its not throwing a code and I dont think im stressing it much considering It wont even perform like it did with canned tunes.

Could my engine running below normal temperatures be a symptom of something wrong? I also did cups at the same time as the injector install aswell, it all seemed to go well though.

Coolent looks clean and good.

No oil/coolant/fuel mixing?
Can you tell a noticable difference between tunes, ie is your stock/econ tune notably different than your street/extreme tune?
Have you monitored fuel pressure since the install?
I'm guessing an oil/fuel delivery issue.

Just throwing an idea at you but flash back to stock, then back into your desired tune. Of course no CEL, that would be to easy... How about these new injectors? Are they an upgraded injector or factory swap? Do you have any way to monitor your AFR's or datalog?

[csdwarf11]

Pulled pcm, unplugged, reinstalled, pull it again and it fixed it.

There must have been a glitch or bad connection

Still trying to figure out the coolent issue.

I feel bad making a thread then figuring it out. But I do still need to figure out my coolent problem.

glad you got it fixed

What is the coolant issue? Not getting up to temp?

Yeah, gauge is low....engine is cool to the touch. I dont want to go hard on the truck with out it warmed up correctly...honestly I dont even want to drive it.

After doing a few race tune pulls on the highway(35psi is a joke, I have to watch out or this turbo is toast o.o) pulled into a store to turn around...popped the hood and the engine was very luke warm. Ive felt my block heater have it hotter then that...

so ive been babying it Ive read about the thermostat housing being bad? and you cant pull it without replacing it?

so I havn't pull it apart yet.
