I had a bigger turbo installed last weekend and I still only get 20 pounds of boost! Could it be a boost leak?

 

if you want more boost you will need more fuel.by going bigger with your turbo all you are doing is flowing air more efficiantly. with more fuel you will need more air aka boost. when i had just a box and turbo i was seeing 28 psi now with everything in my sig i hit 40. hope that helps a little

 

Do you have a j-hook or turnbuckle on the wastegate? If not that is your problem. Stock the WG opens at 18 psi and your EJA is fueling past the 18 psi mark to 20 with the fuel.

Edit
You just put on a new turbo but still check on the WG.

 

i have no waste gate.

 

Check for leaks. Pressurize the intake and any leaks will become readily apparent. I use a 4" pvc cap, a cac hose, and an valve stem to check for leaks.

 

i will give it a try. thanks.

 

i still think you should get injectors either way lol
