Mike what does your cmp pid read at 1200 rpm with the new distibutor?

1997 S10, 06 trailblazer SS LS2 swap, 4L70E trans, 76mm turbo. Factory ZQ8 suspension. 3.08, G80 w/a zexel. With a 0411 swap.
Maybe. I didnt think about that :( Thx for the reminder. Is there a certain procedure and cant I do it with EFILive?
CASE relearn is like crank position sensor relearn.
Whats CMP? Have to ck tomorrow anyways, trucks at shop and Im home now. Thx for the input and help
A case relearn has nothing to do with anyhing but misfire data for the ecm. It does not effect the way the engine runs.

You cant just stab in a vortec distributor at tdc #1cyl and think it is going to be fine.There is a bit of procedure involved since you cant rotate the distributor like you could in earlier small blocks.

So whats the procedure?
Ok so found this :

In part 2, is what they are telling me to do what I need to do. Is tht what u were referring to?
Is GM.CMPRET the PID I need to be viewing while doing this?
How sensative is this sensor up there. I mean they are talking about rotating the dizzy. But the dizzy base only goes in one way, the clamp is attached to the dizzy base with flat sides so that it can only be installed one direction. And the clockwise/counterclockwise rotation is NIL. Maybe a smidge. Is it tht sensative that it makes a huge difference?
Realistically it runs fine but seems lean but it has simply no power on throttle driving. Like I doubt it will climb RPMs at all.
So if this is true and the procedure, ANY time the stock dizzy has the bolt loosened (even by itself and no swap is done) then it will throw it out of whack?
It does not hurt to check the cmp. You said you installed a new distributor and after starting it does not run the same. Verify you are not a tooth off first. Yes the vortec v6 does have the hold down that prevents turning the base while installed in the engine, while the v8 vortec allows full adjustment. It is strange why GM did this. But ther is still some play in there. Parts wear out etc. I assume you dont have the dtc P1345? Like I said it does not hurt to check. But if it ran with less power after a distributor swap, then it is either not installed correctly(a tooth off) or the quality of the distributor itself is not ver good.

Gonna stab the dizzy in there. Then ck SES codes. Then try this CMPRET PID on the scan tool and see where its at. From there I will try to adjust. I see no play in the base really. The hold down is a bit loose to the base but not much in play as far as the bolt hole.
No code thrown last time I cranked it but P0016. Just checked last 2 SES logs.
Bad module?
