Hey I don't mess with the H. P. stuff but from reading this stuff and seeing your mods I bet not enough fuel. After the AIRDOG 150 if lines are large enough you'll see lots more boost. With the modded cp3 its icing on the cake. Put those on first and then you'll need a headgasket and studs. LOL. If I'm wrong it was fun typing this and I can follow this thread. LOL

Doesn't the attitude read the boost from the map or somethin like that? I thought I read somewhere that it only reads up to 40 psi

As Stated above the Edge will only read up to 40 lbs you will need to install a analog gauge to read any higher

How does the computer tell the turbo to boost more when more fuel is added. There is no plug joining the turbo and computer. I thought that boost was predetermined by the impeller size? Just asking i may be wrong.

If it starves for fuel it won't boost to its max. Same as adding a fueling box. That always increases boost and h. p.

Diesels are fuel driven. Turbo boost is a by product of exhaust gas flow. The more fuel you dump in, the higher the exhaust flow, and the more boost the turbo makes. The turbo's job is to provide airflow to cool combustion (EGT's). The higher airflow allows more fuel, which allows you to make more power, it really isn't the turbo making the power, it is the turbo allowing for more fuel that makes more power.
