Slaughtered a Fox
The LT4 KM, is the knock module out of the LT4. The LT1 KM is far too sensitive, and picks up a lot of false knock, which in turn retards timing. If you've got headers on an LT1, you basically need an LT4 KM. Since the LT4's had a noisier valvetrain, they're far less sensitive and don't pick up false knock from things such as headers.

I overlooked your sig. I just know of a friend of a friend who has an LT1 6M T/A with longtube headers (full exhaust) and a tune that went 13.4 at Milan Dragway. I'm sure the trap speed was in the 100s easily as well.
Yeah, I should've been running around that with a trap of around 105, or so. But, I was too scared to launch hard on the 10 bolt. And the outcome was absolutely horrible babied launches. I may have to go out and find a good road to test the Gtech on again today. I haven't even used it since I got my DR's. And that was a while before I got the exhaust done. I can get damn good launches on the street (well on a few different roads I race on), so the results should be pretty good.
Gtech's are usually 3-4 mph off. They show higher than what the car actually traps.
Sounds like your car would be a good match up for mine tspence, I was trapping 95-96 mph in 100 degree weather with like 40-50% humidity.
Good runs though, usually the kids that floor it everywhere in foxes are just trying to cover up the fact that they just have weld in flows. I had some kid in a 5.0 try racing me the other day. He kept flying past until one time I dropped into third and stopped his pull immediately. I got next to him and he wouldn't even look at me.
