Precision Industries/Vigilante
One reason may be that Vig's stall ratings tend to run about 400rpm higher than Yank. So a Vig 3200 = Yank 3600. Folks who didn't understand this tended to criticize Vig converters for being excessively loose. They may indeed tend to be looser than the super tight Yank SS series, but they're nonetheless a quality converter.

I specifically wanted a 2800 so it would be nice and tight. Got a package deal from RPM Transmissions on Built 4L60 + 3.42 Rear + Vigilante Converter. After ordering, PI called me, asked me what I wanted and what mods the car had, and I told them everything in detail, that I wanted 2800 stall speed, and that I was concerned about driveability and wanted a tight converter.
What I got was a converter with 3200 stall speed and that was annoyingly loose paired with my new 3.42 rear (coming from stock 2.73 and stock stall).
Got used to it eventually, but never fully satisfied.
Lesson learned. Next C5 build in the future will be 3.73 and a Yank converter.

Where have you guys ever heard this about FTI? I have an FTI and it is perfectly fine regarding actual stall speed vs advertised stall speed.
As far as people beating up on converter manufacturers for missing the mark on stall speed, if you understood what a moving target a converter stall speed is, youd cut all of them some slack... Stall speed depends upon so many factors and variables that it amazes me that they can get them as close as they do. A converter that stalls at 3200 behind one engine might stall at 3400 behind another, or 3000 in a different application...and so on. That's why they all offer a free restall if need be after you run the thing.
As I reread this post, it kinda reads like a Precision Industries brochure or something. I have zero affiliation with them, other than spending thousands of dollars a year on their converters. I just appreciate a good company, with a good product, and a good warranty. These things, in combination, are a rare commodity these days...
I agree it will be diff motor to motor but if I tell them whats it going behind it shouldn't be 400rpms off.
Now if someone specs a converter for a 400hp car and then installs it into a 600hp car I would understand the stalll speed being off.
Not saying its true. Just going by that if it is.
