Noticed a couple of things that are unsettling, though.
First off, apparently Aaron drilled a hole through the throttle body blade on the one that he installed on my car. I hope the guy I am sending it back as a core doesn't kick it back as being unacceptable this way.
Been doing a lot of reading about tuning, particularly idle tuning and the issues related to getting a *good* stable idle. Every now and again someone brings up the idea of drilling a hole in the throttle body blade to try to resolve some idle issues.
Found an interesting quote that I wish I had known about a long while back in reference to cars with electronic throttle control (like mine). Not that I knew about the hole in the throttle body blade myself until I actually pulled off the throttle body, though....

What time is it when your tuner says to you "a small hole must be drilled in the throttle blade in order to eliminate all idling & stalling issues..."?
Hah! Not to mention that the brass colored throttle plate throttle body isn't compatible with my engine management system anyway, and a supposed Corvette "expert" wasn't aware of that fact.
Mike Carnahan sent me a new tune to do some data collection off of, and asked me to put it into boost a couple of times so he could look at the data. I went into boost in third gear the first time, and then from fourth gear. I also let the car engine brake so I could get some data in those cells with higher RPMs but with vacuum in the manifold.
I think I hear the waste gates in the first run, but not sure. The MAP value is showing that I'm only at 144 kPa which should be only 6.2 psi of boost. There are supposed to be 10 lb springs in those waste gates....
This was the first time I've taken the car to 100 percent throttle.
Seat of the pants impression was that the car seems to pull a LOT stronger in fourth gear than third gear. Maybe just my imagination.

BOY........does THAT sound NICE!
I can only imagine (and be envious of) what that must feel like when you plant your foot!
Lotta time, money, and head (heart) aches have gone into that car thus far,
and it seems like you're almost there! I applaud your perseverance!
Should be one ballsy beast when it's finished.

Yeah, it's coming along pretty well. I noticed that Mike Carnahan didn't just discard my own tuning fumblings in the tunes he is sending me, so apparently I wasn't too far off the beam with what I was trying to do. I've still got that minor cold start instability to get rid of, and the engine is tough to restart if it stalls while still cold. But these are really minor things. If I wasn't such a pain in the ass perfectionist about this, I would just pull the wideband out and just have fun driving the car.
I got a new tune from Mike this morning, but haven't looked at it yet. Finally getting some rain here, so probably won't be driving the car today anyway. Even if it stops raining here, I would have to look at the weather radar and plot a course to try to avoid wet roads from the popcorn style storms popping up all around me. One thing I definitely don't want to do is to kick the gas pedal on a wet road!

That might prove to be ONE INTERESTING RIDE!
I would be content to just see the video of that one.....
I would also like to see a video of how well it does in the snow...

Unless there are some severe changes in the Florida weather patterns, you will NEVER see me stepping foot or setting tire treads in snow. I fully intend to die with never having had another snow flake land on me or my cars.

You've been VERY consistent about that, and I'm beginning to catch up to you.
Wasn't bad 40 years ago when there were less cars on the road, and
the people that were here then KNEW HOW TO DRIVE THEM! Lately, all of the
people that come here from other countries where there is no snow, are driving
me insane with their inability to navigate on the roads for 6 months out of the
year. I think that I will enjoy being in Florida in the winter, even with having
to put up with the "snow-ld birds".
