question about my vehicle strategy and why it changes

Ok so today I spent some time with my truck getting it ready to go into the dealer for headgaskets and studs monday. So I turned the truck from xtreme street to stock and to my surprise my truck was doing the turbo sweep which is associated with the vxcf9 calibration so I diud some looking and on stock tuning my strategy is vxcf9h7 then witched back to xtreme street and street and my strategy is vxcf7h3? Why is this changing? I also put my egr valve back in and on stock I have NO fault codes. Any ideas guys?

The Xstreet you have was written with VXCF7 as a base, that's all.

I have tunes written with VXCF4xx, VXCF5xx, VXCF7xx and VXCF9xx. If it bothers you, or you want the benifits of the newest (from ford) strat, have a new program written, otherwise it should work just fine



As for the EGR question.......... you should not have any codes if everything is wroking right , so what's the question there?

Thanks outlaw, the egr question was mentioned because I thought with the 05 and newer it would throw a egr flow code with the egr cooler deleted?

AH! Now that I've removed my head from my azz I see you have an EGR delete.

Now that question makes sense , I've heard that some will throw a code, some won't

BTW - how's that 84' Benz treating you

I've ran tunes from all kinds of strategies, with my EGR deleted, and no problems here! I've ran VXAP1, VXBC3, VXAP2, and some others. They run fine and as long as my EGR valve is plugged in my truck doesn't even throw a code. Even without it plugged in, the only ones that do throw a code are my Spartan tunes which have the EGR turned ON, but plugging in the valve resolves that.
