Evo 8 won't boost or rev over 4k
 

Hey j am new the the evo forums and an evo noobie I bought my evo about 3 months and and it just gave a problem today every time I was in gear and giving it gas it would sound like the turbo was spoiling but no more then 10 pounds of boost would show up on my gauge! But I could rev the car over 4K and it wouldn't bog down like it would at 4K if it was in gear this happened over night! I looked for intercooler piping that was loose tightend them all down please help this is my dd
