Default WTF is wrong with my tune???????

This was a retune that came from a "leading LS shop". One of the biggest names in the country.

No, I'm not saying who. Don't PM.

Just an example of another big name shop doing **** work.

I think this should be the link, but it just opens a page should the file and doesn't allow you to download it

Yeah it's definitely a hosed file, though I don't know what the issue was with saving it off of my server...

At any rate, I have another one for you guys. This was done by another LARGE shop that does primarily GM performance.

The car had a Fast 90, headers, 224 cam, and D1sc at 9psi. The car swung all over the place at startup, had bad cam surge, and went into the 13's:1 after the MAF maxed out around 5K. These are the highlights:

Odd mix of MAF/PE fueling. What is it a good sized cam only Z06?

Added 2% airflow in the low freq. table and took away weird amounts in the High freq table, huh? No change to the VE coefficients yet left the at dynamic air disable at 4000. Though I'm sure those MAF tables are inaccurate enough to keep it not running good either way.

How well did this car run and how big was the cam?

Pretty good sized cam and heads car. Had too much fuel down low, and not enough up top. Totally hacked PE, and as you said, untouched VE, and dynair disable left alone.

It ran pretty sorry. It was so rich at idle, upon start up it spewed a cloud of raw fuel.

Too much idle airflow. It bucked pretty bad. Timing was pulling the idle down. Timing at idle bounced around zero to +6 degrees or so.

WOT timing is/was higher in the low octane table than the high octane table.

Overall, it was just pathetic.

I want someone to explain this. I stumbled upon this PE table while I was turning off the Column Lock on a 98 Vette. The car was tuned at a well known shop in Texas. This has to be the worst I've ever seen. He said the car runs OK. I can't figure out how. AFAIK the guy is still running around on this tune.

Wow, that's a good one. He must be running straight alcohol.
