ECM psi limits? dealership specs needed
Hemiwolf here...
This is my first new thread here at DF. I'm looking for some help!
I'm considering putting a small turbo on my 2003 Hemi Ram 1500. I have been trying to evaluate what I can get away with using all stock parts. So far I have decided that I could probably run 4psi on stock sensors, stock injectors, stock fuel pump with no problems relating to fuel delivery. I'm sure the engine can handle it though I may have to go to a thicker head gasket to drop compression a bit. My big question is the stock ECM??? Can the 2003 ECM properly detect (and adjust for) positive manifold preasure? Some stock ECM's have fuel maps that run up to 1 bar (14.7 psi) some don't.
I need dealership help on this one...
any thoughts on the whole project are welcome.

Me and a friend are working on a turbo project as well. It is on a 2002 grand prix but I have also thought about running a twin turbo set up on my Hemi. I did not get to far because dodge likes to use speed density instead of mass air flow sensor which in turn you would need to tell the ecm about the extra air being pushed in. plus i have not fund a map sensor but I could be wrong about the map sensor. So from what I found you need to come across a computer to reprogram the ecm. but if you can get past all that you could get alot of HP out of the new HEMI motors and I mean alot. I hope this mit help. And if you do get it to work please post the results and keep us updated with your proguess.
I didn't realize dodge used a speed density system. I'll do some homework on that. I'm used to OBDI MASS setups. thanks for the reply. PS. I now realize I worded my original post poorly after re-reading it.... I meant 1 bar above ambiant air preasure..... anyway.. doesn't matter... I'll look into it. I'm sure there is some way to "TRICK" the ECM into adjusting fuel for the extra air... I'll find it.
