Maybe more like "Rich is safer, lean is faster." (Within reasonable limits, of course.)

I dont know about you but i wouldnt drive my truck if it was leaning out. When i was with Sal with the bad PCM ground and had his A/F gauge hooked up. We couldnt get around the corner from his house with out the truck leaning out and going into a 20 a/f. Then we had to go back and see what was causing it. So i dont know about you if one of the tuners tells you that rich is good lean is bad i would tend to believe him. Also dont know how you can say lean is faster i wasnt making any power when the truck was leaning out. I couldnt even break a 100 in the 1/4 mile which i should have been doing quite easy. There was another time when i was on the dyno with Sal and still had the bad pcm ground. Truck just kept on leaning out and from having the 90mm up to my airraid box that had an 80mm hole was causing a choppy a/f when it should be a nice smooth curve. Im telling you what i was told and have seen that LEAN is Bad and RICH is Good. I mean Lean must be bad if the PCM throws a SES light when you are running lean right.

 

I cannot find your post from awhile ago showing A/F readings with various pulleys and no chips. Can you repost it?
I was running a JL 3lber on an unchipped 2000 and when I did a plug check (TR5s with ~5K miles) the insulators were white and the electrodes gray. Plugs looked lean to me though no signs of erosion on the electrodes (this was after running 103 unleaded in 98* heat). BTW, my exhaust tips were just as black as with totally stock motor. Tips prolly not the best diagnostic indicator.

 

Well I took my truck out for one night of "easy driving" and it ran good. It does run a little more lean (which is not good if it's to lean). But I think it's safe. The computer doesn't like the 90mm maf and the crankcase breather with no chip. But other then that it runs very strong.

I should get my chip tomorrown and then I'll see what it does. I didn't take it to the dyno since I wasn't driving it anyway.

And yes my AF is the one that connects to the 02. and no it's not as good, but if you learn to read them they will give you some info (and save you a couple of bill$$).

I'll keep you updated, but still no pinging.

Also I'm running stock plugs. Maybe this high mountain air is good for something.

 

Well good luck running a 6lber w/ the 90 on your stock program. And yes I don't have 95 dyno runs experience.
High Roller has seen it with his own eyes and he says it's safe. Maybe so, but I have seen enough stock dyno graphs to know that every truck is different. Do as you wish. And look again at those pics of the plugs, Good luck.

 

Didn't MM&FF do their stuff with the stock program???

 

Sometimes I think people do not read the whole post

He said he drives his truck at 5000 ft and at that altitude even with 6 pounds more boost I bet hes making less power than a stock truck at sea level.

I know this , I know a guy who added a 5 psi pulley that drives his truck at L.A.C.R. 2700 ft above sea level, and it ran about
the same times as it did at Carlsbad before the pulley.


What I am saying is that at 5000 ft its not going to need the extra fuel that is required like it would at sea level.

I would give Danny Swanson a call, I know he makes programs for L.A.C.R and see what he thinks about running the extra boost at that altitude

Now if you drive your car at sea level you might be in trouble

I think Ronnie has the true, but sad, truth. My truck does run slower up here because of the air. It does require less fuel but theoretically can run more boost at the same time (but still be slower).

If most of you felt what my truck feels like up here with 6lbs you probably wouldn't love the L so much. But then again I have the advantage that everyone else has the same set back up here... So I'm still very, very happy with my L.

I'm still waiting on my chip that was supposed to arrive yesterday morning.

What is the name and number to that tuner that has experience in higher elevations?

 

Dannys phone number is (310) 787-7800. He is in Torrance Ca.

 

What type of chip does he tune?

 

Danny uses Autologic chips. He also has his own dyno. He tunes some of the fastest Lightnings in the So Cal area.

 

I have run a Swanson chip and was happy with it, but my CUX-1 will no longer take a chip. Maybe a bad circuit in the board, I don't know, but Danny knows what the heck he is doing.

I haven't run a chip since last Thanksgiving and am running the equivalent of 4# of boost plus various other little mods. The reason I pulled the chip to start with was the bad-winter-gas ping syndrome. When I pulled the chip, no more problems so I don't necessarily agree with the assumption that it is dangerous to run our trucks with pullies and no chip. I think it is safer than a poorly burned chip by far.

When cool weather arrives, I will be going to the dyno to get my A/F numbers, but I don't have the slightest concern about running too lean. Will be interesting to see what happens against other chipped Lightnings at FFW/Ennis.

 

Hey Guys,

I see there is a topic I might be able to help on with my experience with altitude and boost. Well as you can see I am an aircraft mechanic. I have worked on quite a few airplanes with turbos on them. When a trubo charged engine gets to high altitudes it automatically adjust the mixture. It's kinda like it is running leaner, but it's actually making up for the air being less dense because of the molecules being further apart. So truly the truck might think it is running leaner, but actually it's not. I don't think this truck can tell how dense the air is, but I might be wrong........

 

SVT Moonshine,

I read you reply from a little earlier. You made a comment you truck needs less fuel. Actually you truck needs more air. If you take away fuel you automatically lose power........

Just some insite on the subject, maybe it will help you with your problems.......
