I've got a 2001 ecsb thats giving me some issues. When holding the brake and fueling it to build boost its a no go. I can pull out and and start building rpm's and then the boost starts to build and it pulls pretty hard. Starting to pull a hill it does the same thing. Just isn't making power like trucks I've had before. I put new injectors in because of fuel in the oil. Even before that it hasn't made power like it should. Any advice??
