Default no problems, is there other data I should include...

this was the first time ive done this so I was pretty impressed with myself. It looked as though though the car was running good to me. actual boost and requested were right on.

Default Looks ok, I think... make it a dual-scale x-axis graph so the RPM and boost have their

own scales... taht way you can see things better

Default You're fine, the boost will always fall sharply between shifts. As far as....

anything else goes, since you're polling the engine computer at a very slow rate, try to measure only one group at a time. I always like to look at intake air temps and exhaust gas temps. Usually 034 and 043 work out well for EGT's...I think those are the numbers, it's been a while.

Good luck with everything. It's always good to see a baseline run for your car and save it for future reference when you think something IS going wrong.

It's just too bad we can only take a couple samples a second, but I guess it's better than nothing.
