This next set of instructions that you have received with v4.0.2 has you do some WOT logging, so we'll see where your car sits now.

It probably is getting some power benefit since most of the calibrations I've done so far just to "dial in" have resulted in a significant correction to the target lambdas.

Gotcha.
When we do finish the calibration process I'd like to do a realistic dyno of any gains.
What I'd like to know is how accurate would my readings be if say I did this: Uninstalled the AP, did a pull, then loaded my final AP tune and did another pull.
Would that be sufficient for an accurate representation of a before and after?

Probably. There are still the effects of fuel trim (which we try to negate through this process), but it would affect both pulls.
The more accurate example would be to drive the car stock for a bit, do a pull, install the AP, drive the car and then do another pull.
I know that isn't practical, though.

New calibration, nice.
A question though. Seeing as I have the original cat, at what point should I worry about idle/cruise AFRs values and such, I have been monitoring them but am not sure where the "cat killing" values are.
The plan is to get a supercat or something in spring, not sure if I can go the midpipe route as I don't want the attention, the shiny blue car is enough :P

CAT-killing is kinda hard to predict.
There are two scenarios where the CAT gets baked: lean cruise and lean WOT.
The lean cruise situation is probably the more damaging since it is sustained, but how lean is lean?
I'd say that if your cruise values stay between 13.9 and 14.7 or so you should only experience minimally shortened CAT life.
If your sustained cruise AFRs are touching 15 or staying even higher, let me know and I'll "fatten up" your cruise values on your final tune.
Those without a CAT will want to cruise at 15 or above up to the point where they experience surging.
Different cars react differently to lean cruise values, so feedback is necessary to tune lean cruise.
My car will cruise just fine all the way to nearly 17:1! Another car here in Phoenix was not happy beyond 15:1. I think Flashwing's car started getting finicky around 15.7:1.

my 6 months went by and i never took advantage of the tuning calibrations because i think that all that tuning stuff is beyond me.
i still think so. maybe in time i can teach myself. it would help if the accessport software would install on my computer. i have vista 64 bit.
