Damn I missed that :)

Yep, map is out!

Thank you very much guys for the help.

Attached is one log I did with mixed driving. Note the dips in Throttle. The car died on me at the end!

All TB values are stock 5.3. Tune is attached as well.

2007 1500 Avalanche with a 6.0 swapped from a 2011 2500 HD Silverado.

I used a 6.0 file from the repository for a 2010 2500 HD Silverado. I kept my TB because the TB on that engine was damaged....

Awesome work guys and really easy to learn. Thanks!

But scanner freezes during a log too much. You cannot get a clean log to reflect on editor! The scanner does not crash, it just stops reading...

Here are two other runs. The first one is at ~15 psi

And this run is at ~14 psi

Hi,

Car is a 402 LS2 with an e40 and a set of PT7675B turbos and meth. PRC 237cc heads, FAST 102mm intake and a 102mm Nick Williams TB.

I went to the dyno and spent around 4 hours without...

I think your WOT issue is related to pump. Better to check for FP during your run.

Subscribed...

I'm in this same spot :)

After swapping my 57mm Turbos with 76's, I need to get rid of those 1000's cc and get 2000's cc. I didn't do it yet but it's good to see what I will have...

Will drop by :)

Hey Sultan :) Long time no see bro!

I would understand if it has aftermarket valvetrain, but it doesn't.

Do you use knock box?

Hey Carl,

What's up man? Thank you for the great tips. I was hoping that this might be some sort of false knock, I guess it's not :(

Hi All,

Car is not mine, it's a friend's and I'm helping him tuning it. So I don't know the inside and outsides of the car. It's a 2008 A6 Cope with a 427 LS3 + Heads and Cam. Compression is ~11.3...

Thank you very much for your great hint. It really helped me identify the main cause of the problem when I went and checked the manifold :)

Yes indeed :)

Found it :yay:

I capped the barb off the intake manifold on the passenger side. After that run, the cap took off :burnout:

Will put another one on with a clamp to hold it in place :cheers:

Hey all,

Car is 2005 C6 with a 402 with an HP Performance Twin Turbo Kit and Methanol. Turbos are T3\T4 57 mm.

We managed to pull 746 RWHP and 911 RWTQ. I got a boost spike during this run...

I just was thinking, on a dyno and with very limited time.. Because time is money here, literally :p

So how do you deal with all these variables on the dyno?

Russ thanks man. This is what you get when you don't build your config from scratch :banghead:

I'm gonna clean that up and start with a new config.

Thanks again :worship:

Hi,

Car is a 2005 C6 MN6, Built 402, HPP TT Kit, Meth.

Tune is 50% scaled but Knock Sensor tables were untouched intentionally.

I safe-tuned the car before doing any WOTs, AFR~10.1-11.2 and...

Ha Ha :D

No need :D

I already heard the story :crazy:

Hey I thought you are in Chicago !!

So after hitting ~11.5 AFR and having meth running, no KR was noticed.

So, Open Dump WGs are innocent

:cheers:

Good luck figuring this out man!

One good question, was the car running fine before you tune it?

I know but I'm just playing safe since this is the first WOT I do.
