has anyone done this? is it good thing to do on a stock converter? Will it hurt or help you any? will the stock converter handle this?

very much a noob when it comes to tuning. any info would be greatly appreciated.

 

I definately would advise against locking the stock converter up at WOT. The clutch on stock converters is pretty thin and weak.....I've seen it.


Locking em up near the end of the quarter like say top of second or bottom of third gear has been proven to knock off a couple tenths but it really depends on how efficient the converter is. If you have a good efficient converter then it may not help much at all.

 

We tried doing this when my truck was on the dyno and couldnt lock it/get it to stay locked.

 

alright well im about to get my truck retuned and right now it is locking up right at the end of second going into third. but im starting to think its hurting me then helping me right now since i dont have a aftermarket stall.

 

i dont recommend it with a stock stall...

 

Doesn't the stock tune lock the converter at WOT?

 

hmm, yea, it does. For an 04 LM7 anyway, it locks in 3rd and 4th at 75mph from 50% -100% throttle. The stock tune also allows the trans to keep the converter locked during shifts. Both of which are bad calls IMO since neither is good for the trans.

 

If I can get my converter to lock on the dyno, wouldn't it be able to lock on the track to?
