Default Low Boost Target No Codes (with logs) - 10-16-2016, 08:04 PM

Quick background on the problem, running JB4 and DCI everything was great, got ********* ** last week installed myself, slapped on map 2 and had very low boost and gasket leak at ** to mid pipe took everything back out next day found out o2 sensors on backwards and some obstruction of waste gate actuator from v clamp, fixed it all up new gaskets on (although one is still leaking slightly at mid pipe which ill change this week but really don't think that has anything to do with the problem) put it all back together and still only hitting 6-10 psi at WOT. I've read for hours and took logs compared it with others and am still stuck, I have 0 codes no 30FF or anything, only thing that came up was 29F5 and 29F4 after i took auto clear off which is cuz of no cats. Boost target is around 6-7 psi on map 2 and the car can make that easily but it should be 14.5, also turbo rattle at cold start but think it is because of exhaust leak, idle is perfect nothing else is out of the ordinary except for being slow. I'm assuming it has to be a boost leak coincidentally happened as a installed **'s but not getting any codes has me wondering, CP and BOV are coming in this week so will see if anything changes. If it was boost leak would'nt my target boost be high and actual boost low, it is as if the JB4 is'nt asking the engine for more boost, any help would be appreciated been bothering me like crazy.
