They're just metal tubes. There's nothing to be affected if tiny metal particles went through them. But, if the ball tips are scored, then they're junk. If just polished and not bent, they're good.

got something new last night
P1400
Apparently it's related to the expected airflow vs what was detected during cold start.
I'm assuming there is another table that i need to copy over.
I did copy over the cat heating table...
or the other thing, but we don't talk about fight club.

Yeah because it needs a proper tune. What did you change from the original tune?got something new last night

The original trailblazer ss tune, it still has the same fueling stuff from the first run.
But it does have that timing map from the 2500hd.
I'll look at putting the trailblazer ss timing map back for now.
Just the 2500hd is so much smoother.
Only real difference is the higher revs.
I have been thinking about a hybrid between the two.
Just knock down that higher load stuff pretty much.
But the hoe has been benched for now, it's clearly not ready for longer drives until it's 100%
As for knock count checks, so far it's a draw between the tech2 and hp tuners.
Hp tuners is nice because of tue smaller dongel.
Tech2 sticks out and i have to be careful when driving.
I managed to bump it and caused a disconnect...

Oh one other thing i changed.
The volume of the intake.
The trailblazer ss had a different volume than what the 5.3 had.
I thought the ss had the same intake, but now I'm not totally sure.
I can try flipping the value back to see if it helps.
But it took several days to get that p1400 to pop up.
Maybe because of the cold starts, i didn't allow it to warm fully because of shuffle cars around.
Focus has shifted to the wifes car.
Routed a drain tube for her catch can.
And i have been flushing fluids, transmission for now.
Next brakes and power steering fluid.
I also found her car had the original battery!
I started noticing a slower sounding start here and there.
So i popped the battery access hatch, found an ac delco battery with no date codes.
So i texted the original owner that we bought it from, sure enough.
Original!
10 year old battery!!
So she got a new one from costco for good measure.

Well, i did some timing adjustments in the tune.
Reduced the overall timing in the 10 degree and over cells by a few points in the high octane.
Really reduced timing in the low rpm high load table.
(500-1000 rpm)
And the high load timing jump, i made that a little shorter, reducing timing for high load overall.
Then went through the low octane timing and matched thst up, and using another timing table to match up the expected timing reduction.
Then knocked a good 5-10 degrees from that.
Seems to run fine, but my low rpm torque sure suffered!
Doing a little logging with the tech2, im no longer seeing that 2 degree of timing retard.
And the misfire map looks clean.
For now it's good enough to drive around town should i need to.
But i have a set of new oem nb O2 sensors on order.
And while I'm in there, it's getting a wideband.
I do worry about the wb being right at the exit of the cat.
I have issues just with the long tubes in the ol vette, those things can be a bit fragile.
And about $80 a pop.
For the hoe, i still might just have an o2 bung installed before what i think is the middle cat.

Weighing in just buying a new wideband (AEM) vs using my innovate wb that's currently in the vette.
I'm thinking this is the one: https://www.amazon.com/gp/product/B0184TSI84
Thoughts?

I have that one in my Chevelle. It works great. To be honest I haven’t messed with any of the more advanced features that it has but for what I use it for it’s great
