I heard of the gains from the gains from the LS4 throttle body and read the thread about the gains from P&P the stock throttle body so my question is which is better and get the most gains from? If I'm going to do one or the other I want the best of the two.

i have the ls4 its a beastly dd, good throttle response, i too was looking into a pp lsj throttle body

I was looking into the LS4 too. Have you had any problems with idling or drivablity?

drivability you have to gradually roll on the throttle no flooring it, thats not my driving style so bye bye ls4

why cant you just crack the throttle open with the ls4 TB? I had the Rebel 3" intake and never bought a ls4 TB so i just sold the intake.

If you are not tuned for the ls4 throttle body, there will be drive ability issues. If you are properly tuned for it, it will drive just like stock.
