Well, I don't see where you ever went full throttle in the scan. You didn't log much information. You have no wideband reading so I can't tell where your fuel is at. Have you asked Jeff at TPE???

You need to post more information in posts like this unless you want it deleted.
Mods? Tune? What is wrong with it? How much power did it make? Dyno? Track times?
So many questions here.
You timing is very low at high load, you are not entering PE, so I assume it is slow because there is a crap tune in the car

Here are the mods . 2002 vette forged 346 ls1 10 to 1 compression with KB 2.6 with 7.5 lbs of boost. 90 mm TB with 60 lbs injectors. Cam 230/234 116+2 588/588. TPS header high flow cats with titaniums. 3.73 gears with 3600 Vigilante stall. Just got the car together and it seems worse than stock on power just looking for a starting point. No wide band yet. Here is my tune as it standsAttachment 16969
That is a config, not tune.
10:1 CR, 7.5 lbs of boost, and that cam? I would think it would be tough to get it to like 93 octane (is that what you are running?).

Attachment 16970 is that helpful?
That should be okay accorrding to Jeff Goos
That file is tuner locked bud.
You need to work on your throttle body and get it to open to 100% It could be your gas pedal has something under it like a floor mat, could be the adapter harness, but until you get that fixed, you can't move forward. You can scan the car without the engine running while monitoring the throttle%.

You need a wideband and a base that gets you into known-safe territory before you pull on that.
Tuner locked?...Figures...Think we all know why now. I would rather an honest professional tuner see my mistakes and correct me than leave it to hiding bs I charged a customer for. Anyhow this thead went no where. Lol

So I unlocked the tune my mistake (when I POSTED IT)and took some advice on TPS. It runs pretty strong and traction is now an issue. This is what I got so far.

Let me try again. Sorry Guys Here is the tune and test run

Looks much better. No knock, but I am thinking you'll find that you're lean at WOT when you get the wideband installed.

Wow, dude 167 degree IAT temps a WOT? Is that for real? Am I the only other one that saw this?

Tell me now that I need to install meth???? The real queen of high mantainence????? What the ?????
To the original poster; I am really at a loss to the tuning approach...
You are using a 1-bar SD OS, which CANNOT 'see' boost rather than a 2-bar setup. Your MAF is not failed properly, though there is little point in having it since it will reach the end of the table anyway. The tune (hope you just 'got it' that way, not trying to step on toes) looks like one of those hack/dyno tunes that means nothing in the real world (on the street/track). You are commanding like bottom 10s in the PE table but getting nowhere close. Looks like there was cheating/lying in the IFR table rather than real airflow tuning, which means that you basically have to lie everywhere down the line since most tables are based around it. Your main spark tables.... I don't even know what to say about them, but I suppose I should mention that the LO table is OEM. The high octane table has to be seen. The car is VISIBLY lean to the narrow bands at WOT. I mentioned waiting until you get a wideband to verify AFR, that's a lot of money to chew up because you want to do it now. I'm not preaching, have just seen it play out like this many times before.
I'd scrap that file and start over again with 2-bar file and tune it from there. Throw the MAF in the woods

I'm not saying they're not high. Just not high for a Kenne Bell. I have the same IAT performance results that you have on my Vortech YSi. One of many reasons I would never own a KB. He's already got it, so might as well try to get it running properly.
On another note, it's funny your name is Vortech and you're talking about your Procharger.
