We changed the cam in my 02 Ls1 and it runs good but when you apply the brakes the car just stalls and kills! It has not been dyno tuned yet it is running off a PCM mail order tune from EAST COAST SUPERCHARGING! Does anybody know why it is doing this?

mail order tunes are basicly only good for driving to the tuner, they are not a complete une because every car is different, What size cam did you install? It will take your factory pcm a while to get used to the new cam. after a couple times driving it the idle should be ok and it will be able to be driven.

Yea that is big-ish cam for a stock cube LS1. A tuner is going to have to dial that in.

So after the tune everything should be good?

Yes, assuming you're using a competent tuner
