FLT Level VII + YANK TC = #1 Qualifier Well I run the IMSM Pro-Dominator 9.50 Index which is "HEADS UP" on a .400 PRO TREE.
With only 4 test passes on my NEW FLT Level VII 4L60E Tranny and my NEW Yank TC I put a "slow down short shifting" program in my 2000 C5 Corvette and went to Byron on Sunday to compete in Race #4 of the Illinois Midwest Street Machine Heads Up Index Series.
I run the 9.50 Index so my goal was to run as close to 9.50 as possible.
First Qualifying pass was a 9.44 in 2900 DA weather which was getting progressively worse.
Second and last quailifying pass was a 9.51 @ 151 MPH and ended up the #1 qualifying run for the Pro-Dominator Class giving me a Bye run in the first round.
The DA went up to 3333 for round one so I decided to "RUN IT THROUGH" to see what it would do with my "Slow Down" program shifting the tranny at 6400 down from 6700RPM. My Run was a 9.38 @ 149 MPH.
This combination is CRAZY it only gets QUICKER no matter what I do!!!

There is no need to lock the convertor at the dragstrip as it seems to be efficient enough to minimize the slipage by itself. I noticed that the trans is shifting very close to the actual settings I put in the PCM. Prior to the yank I had to "fudge" the settings in order to allow for slipage and get the shift points where I needed them. I though I would "slow the car down" by shifting at 6400 down from 6700 so I could run closer to the 9.50 mark but 3rd gear is pulling so hard that it didn't make much of a difference!

I use the electronic locking mech. for highway driving to hold the heat down to a minimum above 55 mph.

So - What do you guys think I should do to "slow the vette Down"?
Lift at some predetermined RPM in 3rd gear
OR
Go back into the PCM and take more RPM & MPH out of each shift like I did before?
Remember I'm trying to run 9.50 with a 9.30 car in the Hot Weather!!!

If It was mine I would kill it in the 60' 1 or 2 lbs of air or a shock click would kill 2/10's for me.

killl the shiftpoints that way it will be consistant every single time. take some timing out of it, that can slow it down too.
I wouldnt count on spinning etc. or just add enough weight.
