Hi guys, just a quick question before I rip off the manifold to check for vacumn leak.
Long story short, had my car dynoed last night, it pulled -15 vacumn w/ 327hp/277tq @ 13psi on stock twins. After a sprited drive home, the car acts very sluggish, and after 6K rpm, it feels like missing, and the car didnt want to pull to redline and power didnt want to pull all the way to redline. I suspect a vacumn hose pop, all the setting from the tunning looked good. Just want to know if anybody knows off hand what vacumn line is most likely to cause such behavior? Thanks in advance. I have almost all the hoses in the rat nests zip tied though...

TIA

 

Did u ever found the leak?
