Ok My problem befor was my ECu it was messed up internally so i got a new one. now when ever it is running i can't rev it up.. i can slowly rev it but when it starts to make boost it will turn off or kinda die.. like bog down, and then idel back up then try to go back down and die.. anything???

 

check timing, maf, injectors, fpr, fuel pump

 

that sounds more like a timing problem then a fuel problem.
