Yes. The bolt came out. My pulleys were hanging on by a thread. Check your torque, don't just torque and assume it's good. Check it warm and cold.

Very possible that it fell out. You don't measure a "90* turn" with torque. You measure it with an angle torque wrench.

Sh!t, going to check mine right now.

I hope you guys aren't talking inHg because you both definitely have a vacuum leak if you are. These motors should be pulling -19 to -20 inHg at idle and can go higher when off throttle in high vacuum situations. Remember not every boost/vacuum gauges reads in inHG and PSI though.

This is what mine says at idle.

Mine always reads like that even before SC. Picture is with E85 flex tune.

user manual states that the 5w-30 can bu also used and that's what many people with FI use on their cars..being in Texas, I would never consider 0w-20

I am not sure how is that even possible, I've attended 2 track events after the KW kit and after many many pulls I didn't run into any issues.. I will check by torque again to make sure..

btw, why did you torque it to 120 ft/lbs? Is that just a random number?

[MAPerformance]

Looks like you might have A/F reading in the LCD screen, and your boost/vacuum in the LED portion.

I read somewhere in this thread others were torquing to 120. After torquing to that it hasn't budged. I even tried to remove the bolt to replace it with a brand new one and couldn't get it to budge. So said screw it, she's staying in.

AFR is on the LCD, vacuum on the LED yes.

(-10) pounds per square inch = -20.3625437 inHG

We have to make sure everyone is talking in the same units. It appears that both of you guys are pulling the correct amount of vacuum at idle.
