Default Where to next?

Im contemplating my next moves for my sig truck. First things first I need to replace the 120 Pensacola injectors..I have never liked them, they run hot and poppy and I have had to rebuild them twice in the last 2 years of running them. I probably wouldnt have run them at all if I hadnt gotten them out of a wrecked truck for a screaming deal.

What would yall do in my situation in terms of new injectors, turbo upgrade, gov springs (3k or 4k?), DV valves, fuel pump upgrades etc. This truck is my daily driver and ranch truck that sees lots of heavy towing, lots of miles and the occasional freeway WOT romp. And will probably see a few hooks a year after the next round of mods.

Turbo-wise the thing thats killing me right now is the wh1c and boost elbow, In order to be able to hit 32-35 psi while in the powerband for towing I have to wastegate so high that its quick and torquey to 70 then run outa boost and have to repeatedly feather the throttle to pick up anymore speed without over boosting.

that turbo isnt killing you. its a pretty good turbo really. run some 5x.012's if you tow maybe a 62/65/12 turbo 4 k springs and 60 lbs valve springs. stay away from DV's they get HOT lots O fuel but hot. i like running a plate in my pump down turn the turbo bast 35psi
