This is frickin ridiculous!!

The LS1's run REALLY well when it's cool outside. If he is stock just race him in the A4 dead spot, depending on gearing. At exactly 30-40mph the A4 doesn't downshift, and it lacks umph compared to normal. If you punch it anywhere in the range of 0-29mph, and 45mph-69mph it pulls hardcore. Catch him around like 30-40, and you should have a better chance. 30-40mph roll is def. not their strong part.

His mods: pulley, cuttouts, gutted cat's, and SLp air lid.

With the asp pulley or equivalent of, almost all the LS1'S drop about .2's, and the lid add's about 10-15 real hp, and the cuttout adds about 10hp. I am not doing ricer math either, this is really how the LS1's respond to mod's. I do think the guy has a stall if he is running 12.7@110 in a A4.
