Xer 273 cam on ls2 !!! guys
the cam is so Aggressive and got a chopy idle i like how it sounds and pulls my c6 with a6 gearbox
but when i stop on a traffic light with D gearbox the cam is pushing the car even while im using the brake !! and sometimes engine wanna stop untill
i quick shift to N
!!
note: i still didnt change the stock torque converter
and the tune im not gonna say perfect but its fair good
and when i start the car while its cold and shift to D the engine stops !!
drivability is really bad
one of my friends told me a 3600 torque converter will solve my problem !! and other says the tune !!

With a cam like that I'm supprised you can stop the back wheels from spinning on the stock torque converter. My old LT1 with a 228 duration cam was on the stock TC and if I stopped in gravel my rear tires would continue spinning until I pushed hard on the brake. Then it would stall out. Cams of any size need to idle higher and they can't to it very easily with the really tight stock converter. If you step up the converter and you're still having issues then you'll know the tune needs to be checked as well.
It might depending on where the tune is set to idle. For example, say you have a tune that wants the engine to idle at 1000RPM and a stall that starts moving the car at 900RPM. So with the car in gear at a stop you'll have the tune trying to up the engine speed to 1000RPMs and a stall that will only let the car idle at 900 RPM at a stop. So at a stop light you're constantly on the brakes either fighting to keep the car stopped or it's stalling out.
These numbers are just an example I picked out of thin air, hopefully that makes sense.

With a cam like that... a 2500 stall would be perfect... if you want a little more peformance, a 3000 stall..... 3600 is over kill for a street car, it will kill mpg, and have excessive slippage= heat in your tranny...... Most guys just buy converters because Joe Blow put it in his car.... You need to pick a converter specific to your engine power band and intentions.......
That jerking and stalling out has to do with the tune as well a stock converter with a performance cam.....So there are couple of issues that ned to be addressed......
Also auto's don't like a lot of overlap......what is your cam installed on 111 or 112?

It must be in your tune or the converter.....
