Putting in bigger injectors is a waste of time if you don't have the air and fuel supply. You need twin CP-3's and a lift pump is you don't already have them. You will also need to upgrade your turbo unless you plan to spray. Sounds to me like you need to watch where you get your fuel and probably double up on your filters. Injectors shouldn't go bad in that amount of time. I put in bigger injectors before I knew what the hell I was doing, (still don't know much but I'm a little smarter then I use to be:D ) and the fuel pressure dropped to about 13000psi at WOT which will get you no where. You would be a lot better off upgrading your air and fuel delivery and leave the big injectors for later.;)
I've got duals, an a5k, and a fass 150
With gm coming down hard on the dealerships up here in Maine I have no chance in hell of getting them warrantied.
