I went back to the repository and got a 2012 Sierra file and downloaded the adaptives and idle spark tables. Same problem.
Its weird that 93 octane didn't give me problems. Sending e mail

Don't quit on me now

Still has the big dip in rpm after a rev. Just before the dip, there is a drop to neg numbers in spark. Where is that coming from?
I reduced idle to 700 and that was too low. I settled for 800rpm...

I pulled file from the repository. Must not be stock---I used a 2012 Camaro because it is not even close to a truck setup any more.
Probably a mistake?
I set the idle for initial startup and...

The oscillating starts after I give it a rev. Rev---let off the pedal---oscillating (1) starts.

Don't know if I can log the PID's. I added the idle speed and pedal position. I will do another scan tomorrow morning.
Thanks

Thanks! Here is result. Still drops to almost 400rpm and then comes back after rev.
Scan attached---I added Engine torque and Idle adapt.

Starts and idles good, even with the lower BRAF. Goose it and let off---throttle drops one time and recovers, but it almost dies when it drops. Got an idea for that one little #^%$%$$

Got it. Be back later. Thanks

E38, 5.3 with Whipple 3.0, 235/250- 115 cam. Starts great, idles great at startup, after a little warmup, I revved it a few times and it went into surge city. When on 93 octane, it would drop to...

What MAP sensor is that? With Linear and offset 300/10.33
Power Enrichment ---Eq Gas and Boost is 1.18 across the board. Boosted should be 1.23 to 1.28
Spark map not setup for 3 bar.
Your log...

If that popping and banging is from a lean condition, get ready to buy some new pistons. Don't do that ---wait until somebody can give you some help. Do you have HPTuners?

Let's see the tune !! Speed density won't cause that problem unless it is done wrong.

Tune and log would be helpful. Where is Ed with the crystal ball?
Did you have it tuned after you installed the blower? If you installed the blower and did not have it tuned, was there different...

Segment swap will not work with this E40.
It looks like you have fuel cut while you have the pedal at 83% throttle and only 1600rpm? Is that correct
Seems like I heard somewhere if you have a...

Only open is used on SD ?
I was reading on Tech that a guy was going to use two fuel pumps, one on a hobbs, and install a timed relay to prevent fuel pressure drop between shifts ??

Why isn't your (closed) VE table populated the same as the (open) ?
Do you have a boost referenced regulator or is it a dead head setup
Are you setup for running SD?

I would also go to Engine Diagnostics--Airflow--P0086 and make that 8000rpm.
I zero out the maf table except the first two cells. Here is a screen shot. I have tried as high as 15 in those two...

Big thumbs up. Didn't know that.
I bought a Whipple that was for a 2019 Silverado from a buyer that was about to send it back. It was for a direct injected truck.
I called Whipple to see if I...

When you say the donor vehicle is a 2019----isn't that a DI engine you are putting into your '03? If so, your '59 is not going to fire the injectors.
I put a 2015 L83 in a 2000 Camaro and used a...

What about 2highpsi ?

I don't know about the calculated torque stuff, but here is what I did to reduce some of the timing dip during shifts. ---Not saying it is correct, but it makes the shifts a little crisper? I have...
