I slid the plate almost full forward and installed the boost fitting that came with the #10 plate I bought. My boost hit 40psi. I didn't feel comfortable with that much boost so I installed a custom boost elbow I made at work now my boost will hit 32 but it isn't as responsive. Any ideas?

Third, STICKS!! Get some 90hp sticks from DDP. They will work fine w/ your truck, give you better mileage, less smoke, and lower egt's.[/QUOTE]
.. you will get more smoke... higher egts... and worse mileage.... my personal experience... and all my friends who have 12v.

running plateless will not hurt the pump, your throttle could stick with a plate and without a plate. Its good to check your return springs everyonce and a while, and to run some good fuel additive.

That fact alone twisted my attitude after I had mine popped before we installed the ones I bought a few years ago.They,DDP,tout their injectors as the correct spray pattern when in fact evry 12v injector they make is based off of a Marine 370.The new set,right out of the box that I had bought,all popped at different pressures and all had dribbling issues and inconsistent spray patterns.They were taken back to the dealer which I bought them from and it took me ALONG time to get my money back to buy other injectors.

I would NEVER install,recommend or send ANYONE to DDP for injectors.......JUNK!

I'm sorry guys I'm an idiot. I had a lot on my mind when I was typing "ddp". I meant SDX injectors. The OP should get SDX injectors. I'm gonna edit my post now.
