Go with Warren injectors you won't be disappointed. I just put 155/80 in my 03 6.0 because like you I tow a lot and just wanted a little more power. I would also high recommened an sct with custom tunes from Eric at innovative his tow tunes are awesome. Just my $.02
Actually I think I miss read some of my research. They arent really, but most of the company's used new ford remans. I domnt think there are really much you can do other then nozzles and angles...... is that wrong???
Most builders have two different prices on injectors. One price the one you say is half of anyone else is where you send your injectors to them and they rebuild them to what ever size you want i.e. 155cc the other price is where they take "new" injectors and build them to the size you want.
