I got the DD II injectors i bought off Jetpilot today via FedEx I already have them installed, it wasn't all that bad of a project. I am loving the extra power, I have noticed they make the pyro skyrocket compared to the old stock injectors i had. Is there a way to rig the turbo to go to 30 - 35 psi as mine is only going to 20-21 right now. I think that may help it out some. Houston we have smoke, at low boost especially in 2nd gear it will boil black, i love it, i'd hate to be a tailgater now, been havin some troubles with people riding right up on me lately around college, now it's payback time. Overall i love the injectors, best thing i have done to the truck so far.
