Going home, i see boost when over 0. So it's not reading a vacuum. If i let off gas in gear, it will show -4. Then goes back to 0. Very weird

Odd, good luck with it! Maybe just a bad gauge or sensor

I suspect its the sensor not sending the correct signal for vacuum. Sent it back so hopefully, I'll get a replacement by next week to reinstall.

Just got back from vacation yesterday. As a follow up, replacement sensor fixed boost gauge. It now reads -16 at idle and up to -22 when off throttle and in gear. I'm worried that I'll have to buy replacement sensors often since I see that sensors have been going out often. If it costs $75 each time, I'll probably just replace this unit to a mechanical gauge when this sensor takes a dump.

Might just be defect, like I said, ive had the same gauge across 4 cars over 5 years.. Same sensor

Went to Fontana drags November 5 and burnt up what's left of my stock clutch running 3 times. Best 60-ft time was 1.797.



I'm #7008. Other is a GTR.��



I beat Scat Pack.



Also beat stock 2006 Corvette. I let off gas when I saw 8000 rpm from clutch slipping, which was 50 feet before end of track. Doh!<br/>Barely made it home with clutch only holding 60 mph in any gear��<br/>

Just got Exedy Twin Disk installed and had Evo 8 3rd and 4th gears installed while tranny was out.
Also, I broke down Sunday and bought S2 and 5041 springs...
Install and retune in January (planned).

I think they're on back order so I'll be waiting a while. I got HLA Pressure Regulator and ARP head studs. Both were easy to install.

I did my ARP different than others. I used screw driver to push paper towels down thread to soak up oil and then used the lube that came with kit. I hand tightened and removed to add more. Then i tightened to 50, 60, 70, and then 80 ft-lbs to each one. I used lube on bottom twice and bottom part of top half where washer and nut will lock. I will let it sit 24 hours and retorque 80 ft-lbs again before reinstalling the valve cover.



Here's the HLA PR installed.

I also bought this valve spring micrometer to check each of my valve spring clearance to make sure I have 1.55". I'll probably put together something to compress each spring to measure thepressure each speing exerts. This way, I can match up the springs to the valve gaps.


Valve spring height micrometer.



GSC 5041 valve springs and titanium retainers

I retorqued my ARP head studs at 80 ft-lbs again. Some actually turned a tiny bit! Interesting!
I'll check again tomorrow to see it bolts are fully stretched. I'm actually surprised.
Maybe enough oil was in thread to mess things up a bit?

Congrats on making the power. Judging by the parts I have a feeling we were tuned by the same person here in SoCal. I made similar numbers on a BBK Lite, GSC S1, 3" RRE Stealth turbo back, Mil-Spec 100 cell cat, AEM intake, AEM 320 fuel pump, and RC1200 injectors.
