When change the pulley. What more on the engine do i have to change?

 

I'm going to assume you're running stock boost levels currently. The 4# pulley is going to be forcing more air into your motor. A properly tuned chip (by a REPUTABLE L tuner) is going to account for this and adjust the fuel and timing tables accordingly which will enable your motor to take full advantage of the extra air it is seeing. So to answer your question...YES, I'd definitely get a reburn. I believe Johnny Lightning deals with the Diablo brand chips, which would prevent you from having to go out and buy a completely new chip plus pay for the file to be burned on to it!

Good Luck and enjoy your newfound power!
