Default All new injectors or just nozzles?

Sorry everyone I know I ask a lot of questions. Just trying to learn as much as I can. Should I buy all new injectors which I know is expensive or can I just get new nozzles for HP gains without heavy modifications to the truck?

Alot of folks put nozzles in when the factory injectors fail. Most likely your injectors will eventually fail. For HP gain the nozzles are what makes the power. What are your goals for the truck? Whats it used for daily?

Can send your injectors in to Don M, and he can reman them and do the nozzles for a reasonable price.

the process of Don M repairing injectors is questionable to say the least. He makes a great nozzel but his repairs are far from satisfactory....And chances are you wont get your original injectors back. There's plenty of documented information proving this. Talk to some of his "used" to be dealers.

My truck has 125k on it now with stock injectors. Daily driver pretty much. I have a little ranger but im letting a family member borrow for a while so im out that option. Right now im looking at a mod. CP3 because the stock one is shot, then an exhaust. Gauges next then a clutch followed by a smarty. Then I will start looking into turbo, intercooler, headstud, and injector upgrades next. I definitely dont want to break anything by upgrading one thing and ruin something else because of it. I need to make an upgrade plan for my truck soon.

my 05 had 60k on it and i just put the ddp 90 horse tips and it was like the difference in night and day with power. but i would just go ahead and get the whole injectors and tips. there expensive but ive been through 7 injectors so far. there just really fragile. make sure you get a fass with the filters it'll save you alot of money in the long run
