Cant reach Full BOOST??

Ok well i just installed a new evo16g ported and modded flapper,tubualr headers,2.5downpipe with test pipe,2.5 exhuast,ported o2 housing.Now it seems like when im at 3k and boosting to 10psi it start to stutter and i guess jolt .From what ive read in the other forums it CAN be bad plugs,wires,coilpack.But everything was working perfectly before i installed it.I was wondering can a big boost leak from the side mount to the turbo also cause it or a bad o2 sensor in the o2 housing?Thanks

All my stuttering/jerking problems have always been the cause of a leak somewhere or a hose clamp I forgot to tighten.

Most likely a boost leak in the system somewhere.

could also be an exhaust leak, did u replace all the gaskets when you did your turbo, and 02 housing? and did u properly torque them?

All my gaskets were in perfect shape.I changed the plugs today and that didnt help.So im guess its a big big big ass leak.Im gonna check it out!
