Just installed dragon flow 275hp injectors and custom built turbo. Truck runs the same! I tried to run a quad adr last summer did the same thing! no more power no smoke nothing. No codes either. A smarty will make some more power and little smoke before it builds boost. Anyone have any idea what my issue is?! I have owned this truck for 2 years and put 15k miles on it its got 136 now. It runs drives and never skips a beat BUT will not make any more power is this thing cursed or something?

All fixed now. The local diesel shop (joke) sold me stage 1 injectors. They swore they where right after I bought a brand new injector pump changed ECMs map and ait with no change. I took the box googled the part numer to find I had 50hp injectors. What a run around ha. So now I have what I'm told 175s who knows what brand that are supposed to be ind injection tips but I called and they don't sell just tips and the shop took my cores and put them on so it smokes and pulls 50psi now but still not what I was hoping for so after that I have 750 into injectors that I don't even know what they are

Sucks when you try and put a little $$$ into your rig and something like that happens. Well at least you found the problem. Surely not what you were expecting....
