I am loving those datalogs, Bill.

Didn't get a reply over on PSN so maybe I'll put it here...anyone? Is 250 psi difference in ICP a big deal?

Great results!

I highlighted where you say that run #1 was your favorite yet run #3 was by far the smoothest. Why is that? I see you mentioned that making power with ICP less than 3000 is a good thing but is there really that big of a difference between 2900 psi and 3150 psi? (Yah, I know...250 psi, right? Duh...). Does that 250 psi difference make a difference in the longevity of hard parts or the oil or both - or will it not even be noticeable over the long haul? With all three runs being within 6 peak hp of each other it seems like the smoothest and broadest curve would be desirable?

Was the turbo completely stock? It looked like you were hitting a max of ~22lbs boost according to the map sensor but that looks like it was a "tuned" max. What kind of boost numbers did you see?

After exchanging PM's with Cody it seems he is very impressed with the "streetability" of the stage 1's and these tunes and has me pretty well sold on going this route, for MY purposes, in the near future.

Good Stuff.

Given the "hydraulic advantage" of about 7:1 inside a stock AD injector, it equates to about 1750 PSI of fuel injection pressure.

It is a completely stock turbo. The 22 PSI of boost is read from the DLC so it's what the computer is "seeing". That is the mechanical limit of the stock MAP sensor, so it's all we get to look at. A mechanical gauge plumbed into the intake tract would likely show about 10 PSI more than that. Not that 32 PSI is good, but that's the reasoning for the ONLY 22 PSI showing up in the datalogs.

Thanks Cody, figured you would see this here.

32 psi makes sense but doesn't make for lengevity! Yes, I understood the boost reading maxing out, just was wondering what the mechanical reading was, thanks.

I like the smooth curve of run #3 on the stage 1's myself even though the ICP was higher.

Will a package purchase be available for injectors and tune?

Was looking to pickup FU1 when I get back from Afghanistan next month. But with seeing this would be inclined to purchase a set of stage 1's and what ever tuning you suggest FU2? Great results pretty much exactly what I am looking for!!!

Looks good Bill!

Keep the updates coming.....

I have a feeling a "stage 1 package" would be a hot seller. Just sayin...

Hope to see another update when you have the chance!

Speaking of which, I am in the market for stage 1s and a phoenix chip. Would you be interested in selling the stage 1s from your build once you upgrade to the stage 2s? Throw me a package deal for your slightly used injectors and a chip?

No window shopping here, 100% committed to purchase.
