im only boosting 7 pounds can anybody help me please

 

Is your car stock ? .... in all gears ? .... more specific. What does your needle on your boost gauge sit at with the car off ?

 

it has an intake exhaust and blow off valve and it sits at zero when its off. when i hit the gas on second gear it jumps to 14psi but when i get to 4000 rpms it spikes down to 7psi on all gears

 

if it stays steady at 14 then drops of to 7 at 4000 rpms, because it is at 4000rpms and not at redline i would say u have a boost leak, might want to tighten ur clamps.
My car also does this is a way i spike to 15 and hold it at 15 until the tach. gets close to redline then it drops to 11-12, the car does this because there is a crappy wastegate on our turbos that cant hold 15 psi very long.

 

Boost leak +1

 

so how do i fix the boost leak

 

Tighten all clamps.....if you make a boost leak tester it will narrow it down for you.

 

you really dont need an aftermarket wga. install a bleeder or boostcontroller. hook it up right tho. everyone will tell you to just t a line off to the wga. youll still spike that way. bleeders are simple, cheap and get the job done. take the two lines off solenoid 2 (green and black) t those off and run a tube through the last hole to the bleeder. get some kind of cheap flow controller in the line going to the bleeder. make sure before testing your boost turn the boost way down on your wga and on the bleeder and test until your running at 14 solid

 

the moparblue platedoes have a tendency to leak. but +1 on checking all your connects. you can also rig up a home-made boost leak detector. i would give you a couple links but the silly search feature isnt working right now
