I have a 2.6H KB with a 3.25" pulley, JLT high boost intake, SCT 3000 MAF, BBK twin 65mm TB. Stock exhaust manifolds off road H-pipe and Magnaflow mufflers. Stock lower. I also have a Motoblue idler.
I have tried 3 different boost gauges and they all read 15.2 - 16 PSI. According to Kenne Bell's chart this should be a 20 PSI pulley. No hint of belt slip.
My engine is coming out due to a headgasket and ARP headstud install. But the car made 607 rwhp how it sits. I hear the actuator could be bad, how do you check this? Anything else I can check while the engine is out?
Thanks,
Jeff
