I just replaced my injector nozzles (re-balanced them myself), deleted my EGR, and replaced worn vacuum hoses/connections. I think some of my vacuum connections may still be a little loose though..



I know I still need to vacuum test all of the lines, however after doing all of this work, I have noticed a significant decrease in my power. Where should I start? Could deleting the EGR have negatively effected the turbo performance (I can't hear it as well as I could before)? Should I be looking at maybe a boost leak or clog in my exhaust? Any help is greatly appreciated!
