05Silver,
Thanks for the info man, I think we'd all be stoked to see what kind of difference troyer's tunes make. I, for one, am using this thread as a personal sticky for when I can afford to get the xcal. I'm also interested in finding out exactly what all is involved in the tunes, ie simple plug and play vs datalogging as described. What all have you had to do thus far? Was the laptop just one with a wifi card? Any other input would be well rec'd, so thanks in advance!!

Hello Steve (Rogers),
First - your highest power reading was actually 249+ HP - in round numbers, about 250 HP - and those are *excellent* power levels for a truck with nothing more than a tune and the AF1. That shows about a 30-40 HP gain at the rear wheels in the *peak* power, which is precisely what it should do. So the power already looks excellent - as it stands right now, our tuning is doing an excellent job.
However, some the other data is pretty bad, unusable, actually - you need to call us about this. For example, we have absolutely zero usable A/F ratio info. Pictures of graphs are useless - we must have the exact A/F ratio every 100 rpm, as we point out in the docs, and specifically, in section 5-C where we talk about what must be on the tabular printouts, and I quote:
"c.) A “tabular” printout - meaning a page with several vertical columns of data with NO charts or graphs, just text, showing the exact A/F Ratio, HP and TQ numbers in 100 rpm increments, from the lowest rpm tested to the highest rpm tested. I.E., this is a page of text with several vertical columns of data - one column would be engine rpm in 100 rpm increments, then another column showing the exact A/F Ratio every 100 RPM, another showing the exact HP every 100 RPM, and another showing the exact Torque numbers every 100 rpm."
That is standard SOP for any dyno, they all output those numbers in 100 rpm increments.
And the fact that those A/F's from the dyno have to be dead wrong, as they do not even come remotely close to agreeing with the data the O2 sensor voltages report (which is exactly the opposite, that the truck is running a bit rich in some places) or the power it is making. There is no way it would be making anywhere close to that kind of power, not within 20-25 Hp of those numbers with 14:1 - 16:1 A/F's - and just by the shape of the graphs it can be seen that there are big problems with the A/F info.
However, your datalogging thru the OBD-II port using LiveLink & your XCal 2 worked *very* well!
Basically, everything *you* did is fine, and as it stands right now, that truck is making exactly the kind of peak power it should be making - we might pick up a little bit more if we tweak it a bit based on the O2 sensor voltage data, but overall, it's behaving very well in terms of power & performance, it's gained quite a bit over it's stock power.
I need to go over some things with you Steve, so I suggest giving us a call this next Tuesday - with the Dyno Day (actually, the entire weekend) coming up in 2 days, we aren't going to get to any changes before then anyway, so I'd suggest giving us a call Tuesday so I can talk to you personally about all of this.
So...........congrats on making excellent power, and we'll discuss your data next week!
