Ok I'm new here but just had to find someone who knows what ther talking about. I just did alot of work on my 90 spirit 2.5. new 50 trim turbo and manifold from turbos unleashed. Fuel pump, injectors,cam,stage 5 cal from fwd performance. Runs great! But very low boost! And only at very high rpm. Like 4 or 5 lbs. What gives?! Boost gauge shows vac and boost. Air fuel seems fine. Turbo seems like it's not spinning fast enough. Could it be waste gate or the disconnected egr? Everything s great other then the boost issue.
