I at this point am thinking you are assuming the timing is advanced.

I've not chimed in on this one, but I am eating it up and following it very closely. It pretty much all makes sense to me -- I spent my first 2+ years of college studying engineering. 
Cody, you're doing some good work, and I encourage you to keep it up!!

OK, How do I put my post(s) on UnMute???
Many of the posts are geared at cold temps & cold starts. Maybe I need to ask or word my question differently. Tonight for example we are talking 9~12 degrees for a low temp. If I change my CPS it would be in the cold driveway (I'd try to do it in the warmer part of the day). But it doesn't seem that anyone will say or hint at how the Blue CPS will or think it would preform when the weather gets warmer?
I don't want to change out the CPS twice a year. I travel much less in the winter (Oct~Mar) than in the summer (Apr-Sep) about 25 vs 75%. In winter I'm almost always unloaded, in the summer I'm not loaded as often (13k+ 5er) as I'd like - but I'm confused by the posts. I've seen very few (1) posts that address engine HP & Torq guesses. How would it do Winter vs Summer?
So I guess that Blue came out on Oct 1, so nobody knows how it'll act in the summer or warmer weather. Does this mean that April 1 this thread is out the window?
Before I asked if anyone has hands-on knowledge how the blue would act in the summer and loaded, very few responded. So I'll reword the question.
How do you think the Blue CPS will preform in warmer weather under loaded contitions???
Thanks

Really the best way to know without having a lot of diagnostic equipment is to have a black one, a blue one, and a heavy load. Then go out on a nice hot day and find the biggest mountain pass. Drive up the pass pulling the load, measuring the EGT and boost. Change the CPS, go back down the pass and drive back up again, recording all the readings again. You have to do it on the same day and as close together as possible to avoid environmental changes skewing the results.
I for one am not curious enough to go through all that.

I would expect the changes to be minimal since the blue cps is already being used in the engine for which it was originally designed. I'm sure weather or temperature conditions wouldn't have a dramatic effect on it as the engine it is currently being used in probably hauls heavier loads in all conditions than anything us with the 7.3 are hauling.

Has anyone installed one and it not work in their truck? My truck showed signs of cps failure, so I installed a new blue one and still nothing. I do notice though while cranking the rpms come up just a little.

i Am Taking My Blue Cps Out. Since Installing It , I Have Not Experienced Any Added Performance Or Milage Gains. As A Matter Of Fact, I Don't Really Think It Has Made Any Difference At All. Neither Positive Or Negative. I Was At First Entertained By The Fact That The Magnetism Was Stronger And That It May Never Go Out On Me Or Last Longer Than The Stock One.
But Now, Quite Frankly, I Am So Tired And Overwhelmed By All Of The Talk About The Blue Cps That I Am No Longer Comfortable Using It. I'm Tired Of Worring About Wheather It Should Or Should Not Be Used. Is It Safe For My Engine Or Is It Not. What Good Is It If I'm Not Gaining Any Benefits From It Other Than Grief About Wheater I Should Have Ever Put It In Or Not.
I'll Stay Tuned On The Subject, But For Now .... i'm Taking Mine Back Out!!
