I have Sam's tune on the car right now but we can't adjust it. It's idling at ~600rpm.

What was so general about my statement? A car will run at idle or regular (non-boosted) driving at practically any afr. You could cruise full lean of you want or dump fuel into the 10's. Should you do that? No but it won't kill it. Yes you want to aim around 14.7:1 for idling and cruising but there are variances that will make that impossible to do that all the time.

Boost is a different story. But why would running .2 more air effect it to the point od being up driveable? Guess what it won't. It won't blow the engine up. Will it be sub optimal? Maybe Idk I dont have enough time on a dyno with the car.

Again I was posting limits, so he could ease his mind. Like "oh its not exactly 11.5:1 no worries" now if it starts creeping past then in full boost then its time to go back to a tuner.

Like I said in the previous post you don't have that much time FI with this car ,when you go tune your buddies single turbo richen up the top end and watch what happens
As far as genral I told you Dm will worry if you don't give him info that is on the money there is nothing wrong with your afr statement but you don't post on this thread enough to understand the full impact of my statement "on the money"

@ 600rpm is partly why your oil pressure is a little low,but you said when you blip the throttle it will go to like 40psi which is fine.

Then you should have understood this conversation from the beginning.

Just a miscommunication

I'm not sure. I would have to ask Chris (the tuner)

Also still need an answer on this if anyone knows.

The Innovate gauge is the same on mine,as far as the dimming check your ground to the gauge and make sure all the paint or whatever is there is removed to get to bare metal.

Also any opinions on the Motordyne manifold? Worthwhile?

Some it takes a little away from top end but fills in a little in the midrange.

[dmhenderson]

Eh. I'll just keep it and swap out the HFCs for ART pipes. The MD manifold has a bulge if you try to mount the stock engine cover anyway.

So I woke up this morning after not driving at all yesterday (due to rain). Let the car warm up and drove to work and now my oil pressure is much higher. 40 at idle and 80 when driving.

What gives? Is that a function of outside temperature?
