my friend is boosting 7.5 lbs on the greddy sohc civic kit...he has an automatic btw. he floors it, the boost peaks at the 7.5 lbs (i fegot what rpm but its in the range of 5200-5700 ) and then slowly fall offs as he hits redline...it peaks at 7.5lbs and goes down to 5lbs b4 reline. this normal for this turbo to do this?

 

What turbocharger?

 

Might have a boost leak somewhere. The greddy kit should not have trouble holding 7.5 psi till readline I dont think.
