So you heard the story... My new built 4L65 took a dump (5 pinion) on day 3 (basically the 1st time I got on it). This gave me a good chance to send back my new PI Vig 3000 rpm stall and have it upped a few hundred rpm. I'm not sure what they're calling this one, 3200 maybe?

Anyway, let me know what rpm you think the stall should be "flashing" at. I was thinking if its a 3200rpm stall, it shoudl flash at or around 3200rpm. Am I correct in my thinking? So when I let off the brake, then mash the throttle, it should hit 3200rpms right away, right?

 

no if it a 3200 stall it will flash around 500 more for ex-- a trailblazer vert stall to about 2500 to 2600 but will flash to about 2800 to 2900.12sec5.3 had a pi 2800 i think and it would flash to about 3000 3100 you may want to pm him and get the right numbers i am trying to rember.i know he loss 1.5 tenth going with a yanks

 

Interesting. Ok, so it's worse than I thought. For some reason my "3200-3300" stall is "flashing" at 2300rpms. Why would that be??????

 

My thoughts, If I understand stall verters after tons of reading. A> Bad Re-Stall by PI. B> Your truck isn't building near the torque low end they think it is. C>Misunderstanding on vehicle weight. They think you're in a lot lesser weighted vehicle.

2 stalls > Brake stall. Point (RPM) at which the vehicle will start pulling/turning tires with brake applied. For a 2800 stall this should be about 2800. Flash Stall > Point (RPM) at which the verter will flash to from a punch assuming good traction. For a 2800 stall would think in your big *** vehicle around 3200 rpm?

 

Correction Randy, that would be ~.2 (about 2 tenths) not 1.5 (second and a half). That would put me back in the 14's!

 

KY - I did a couple more checks. It does "flash" at about 2300rpm. I then did a quick brake-stall and it built boost very quickly at hit 3000rpm and beyond so I let off the brake and took off. Too afraid to sit there and build more power for fear of blowing the trans again!

I did this a couple of times and it's definitely brake-stalling beyond 3000rpms. Once I get more *****, I'll see how high it's really brake-stalling. I just think it's odd how low it flash-stalls. I wouldn't doubt your statement (B)on them not knowing how much (or little) low end torque I'm making at those rpms.

 

Ok, I tested the actual brake-stall. It's at 3300-3400. Flash-stall is at 2300rpm. Odd......

 

my vig 3200 got upped a few hundred rpm but acts like yours...weird huh...it did the same before the restall....but i did get a 1.57 60' in it last weekend..f-body though..not a KONG weight truck

 

I have a TCI 3000 stall in my truck with close enough to the same weight truck as you and my 3000 flashes(punching no brake stalling just letting off the brake and punching it) to 3300 or so you definately need to call the mnufacturer and tell them your problem this is not an ordinary thing your stall should always flash higher than when you brake stall it atleast from my personal experiences.

 

A turbo changes things though. Flashing it doesn't let it build any boost. Brake stalling it does.
