Ok, so I have a fully built 84mm B18C1 and a T4/T67 on it attached to a Full-Race manifold. The engine has been running strong and fast since having it tuned. Most of the time in 1st, 2nd, or 3rd gear, when boost kicks in, it spins the tires. This brings me to tonight.

I notice that the car is idling a little funny and figuring it is just me being paranoid, i forget about it. Then when I am driving home, I decide to floor it a little and have some fun. I notice 2 things: 1. the tires do not spin 2. the boost is struggling/wavering according to my boost gauge. My question is what could be causing this. My boost is set at 15psi and reading my boost gauge it is telling me that I am barely hitting 10psi.

Help me and please tell me this isn't a big problem, lol.

that is bad ***!!!

 

sweet, does anyone have any other suggestions as to what could be causing this ?

 

boost leak, 4 sure. You can make tester yourseld with a rubber coupler, a pcv endcap and a valve stem. Attach it to where your turbo would connect to the charge pipes and pressurize it with air.

Listen for leaks...
