| Wow thats one long sentence!! LOL j/k. With your injectors, they'll still be under factory warranty. Just take off the edge and make sure everything with the motor is back to stock, and take it to the dealer. If they're bad then they'll replace em for free.
If your sayin you want to "upgrade" them, then thats a different story. The duramax injectors are pretty darn good performance wise and shouldn't need to be messed with unless you plan on makin some big time power numbers, but even then they'll be towards the bottom of the list. If you want more power outa your truck, look into some gears. Somewhere close to 4.56's or 4.10's, not sure, will get you close to the stock ratio with those big ol tires. That'll help some. Then upgrade your tranny and get a PPE tuner or EFILive. |
