03 silverado 5.3L

[sting5841]

Hey everyone I been working on my 03 5.3L to get it fast I'm worried about my tranny takeing it. I have K&N, Flowmasters, Hypertech. I've run a 15.5 but I want 13's I'm planning on a ATI Procharger and I've orderd headers and a new intake has any one else done any of this or running a predator programer

Also I've heard that LS1 edit will remove the torque converter management so we can shift harder is this true?

13's will be tough on the 4L60E tranny in the stock form...  I'm not saying it won't take it, but it wouldn't hurt it to add a little beef to it if you plan on running it at the track alot.  :thumb:

I think you'll be OK until you add the Procharger.
