Leaning out some, coupled with the load of WOT in high gear, is probably causing the ECU to pull timing. Do you have any data logging gear?
Even after you have a shop tune it, data logging the car at the track is always a good idea. I don't know of a shop in the NC area that has an eddy current dyno, so you're probably going to get a tune based of the way a dynojet loads the motor. It's still going to be great, and be way better than it is now, but the load it will see on the dyno is different that it will see going down the track, so data logging it (at least in the beginning) is a good idea.
Good luck with it. PM me the next time you are heading out the track. Jonecap and I hit Rockingham and Nam all the time.
Thanks for chiming in Josh! Tuner said something similar to your thoughts on it. I have a Moates data logger on the way and should be here Wed. I've decided to bypass the dyno tune and just do runs at the track with the data logger. I also have a Jet cable coming so I can upload the new tune myself. This way will be much slower about tuning the car but like you I feel in the long run it will be more accurate. I have no doubt there is a lot on the table left to gain.
Hey, if you guys decide to go down there PM me and I might tag along. I have to get the car running better though you two will make me look bad if I don't.
On another note.....I emailed Weatherunderground about the weather stats down there. They lost the weather station that was providing the data. They've switched to another one so the automatic weather is back on the Drag Times DA calculator for The Rock.
Here is my actual DA for this past Friday the 11th.
