It will put the proper #'s into your Base Running Airflow under idle. You start logging then start the car cold don't touch the gas and let it idle until car is well up to temp. You need to it for park and in drive. You will see all the fields being filled as the temp rises. here is a pic of table on hptuners.

OK. Sounds pretty good, but from what I've been reading, the VE's have to be right first, and I don't think mine are. Wouldn't it just screw it up if the VE's are still off?

Sorry to have to give this update, but on the way to the dyno, my daughter called. Her car died, smoke pouring out the hood. Radiator split in half.
Then I got home, and the pool pump was shooting water out a cracked housing. Damn this AZ heat!
Then I go back to my car and the burnt egg catalytic converter smell is horrendous. I think I burnt up the cats.
So, I'm gonna dump the cats. Won't have any results until then.
Sorry guys.

If it weren't for bad luck, you wouldn't have any luck at all.

Ok so I dropped the Y and cats are toasted. I grabbed some 18" pipe at AZ just to throw on the collectors and try to get a decent number. Caught him as he was about to close and begged him. Got one pull only.
So, the disclaimers - basically open headers, 197 coolant temp due to no cool down time, low 12's AFR, 108 ambient, 26 barometer, 12% humidity, 1.07 SAE correction. Wheel balance affected the pull above 100 something MPH. Smoothing at 3 and it still affected the graph.
474@6320, 417@4890. To be honest, I think it caught a peak at 6300 and the real number is 470@6500. It never really fell off, I just didn't trust going over 6800. So, without further ado or guilding the lily......

Oh and the old motor pulled 370. Heads, intake, and move to short travel lifters were the main power adders. Same cam. So figure the MMS220 heads + fast + short travels are worth 100 over the hand ported stock heads, BBK intake, and stock lifters.
FWIW

Probably the hardest part is from a dead stop. If I don't give the car in front a head start.....
With your corvette exhaust, you'll probably do better.
I would say on this set up, 500 on stock cubes can be done, but it needs to be perfect. Light clutch, dual exhaust will be necessary. Also, this is a medium sized cam. You could throw a 240/246 cam at it to pick up the power, but I think I would lose midrange, and I like the midrange how it is.
The most fun is when you have a passenger who thinks they like fast cars, and you pin them back. They look like that Jeff Gordon Camaro test drive video that's been making the youtube rounds.
