So I went to the track on sunday (I know kinda late with this post). But in my 01 5.3 RCSB, I managed to pull a 14.9@89 mph with no weight reduction and bald Toyos.
Mods: 3k Stall Fuddle and a Muffler
For the record I was turning 2.2 60fts, and the converter was locking as it shifted into 3rd, I think with a 2.0 60ft, and stoping the converter from locking a 14.5 is in the near future...or I could just STS it and shoot for some good 12's

 

How do you like the Fuddle? I need a new converter, the TB isn't enough, but my TCI was too loose for my taste. I was also looking at a Yank.

Btw good times for a relatively stock truck.

 

What is required to make the converter not lock????

 

tuning

 

Holding the brake pedal slightly just as the trans shifts into 3rd gear and holding until the finish line will prevent a WOT TCC apply, I did that before I got a WOT TCC apply tuned out. It was worth a tenth in my truck in the 1/4 mile.
Make sure you dont hold the brake pedal hard enough to actually slow the truck, just hard enough to illuminate the brakelights.

Matt I liked how the Fuddle drove. I had the TCI 3K just like you then went to the Fuddle now I ahve a Fuddle 3200 in there Ill let you know how I like it. John can build it with a special stator in it to make it feel "tighter"

 

Thanks

 

I like the fuddle...it felt a little loose for the first couple thousand miles(although it was the first time I drove an auto with big stall, and this is my first auto vehicle), but I love it now. For the record I think with new tires (something better than Bald toyos) no WOT TCL, and no TM I should be able to pull, a mid 14 with a 2.0 60ft

 

1/8 mile 9.09 @ 78 mph
Don't have 1/4 mile near my house
Still working on getting faster.
