ok... My kit is almost complete... just need injectors, fuel pump and my ecu chipped.. I was wondering what is a safe psi to run for a daily.. im not lookin to be super fast.. but just quick Also ... Do I really need a car street tuned or can I just simply let the tuner know my set up and get the ecu chipped and ride?? Heres what my kit consist of

Turbonetics T3
Drag manifold
Drag down pipe 2.5
Drag piping and intercooler
Delta gate waste gate( soon to be tial)
HKS Bov
440 cc injectors
..

Also have another question.. my car is a 99 dx .. so both the O2 sensors are in the front on the exhaust manifold... my drag manifold does not have a bung for an o2... it does have one on the downpipe though... will i have to extend my o2 wires to reach the down pipe?? or is there an easier solution.. Thanks
