Good Day at TnT - any feedback?

Finally got out to TnT yesterday to check the changes in the car and had a bit of fun while at it. By the end of the day had the car right at 12 flat, still had a more in it. Track was at 5000 DA, here is what I figured out.

Timing - wow this thing loves it, maybe its just the altitude 40 degrees. Started on 91 still liked it. Mixed 2 gallons of 110 with it at the end, bad for baseline

Needs more jetting - just didn't get this completed

Tires - M/T 295/65/15's street radial - By the end of the day we where down to 12 lbs, still only a 1.75 60' - bit of an issue

Shift points - the 440 likes 6200, bit of lean pops, need to clean this out

Coming through traps at 5600, needs to be more. Thinking of changing to slicks 28-10's possibly. This will change trap RPM and 60' times, so will keep some of the other changes for next time.

NOS - Had problems with the NOS solenoid sticking closed (better than open). Started off as intermintant, then just not working, back to working.

On the launch my partner was saying the rear didn't transfer as much weight as he felt it should, this car is /6 suspension with a pinion snubber.

Future changes: (Any insight from from you all?)
Slicks - 28-10's -

Work the lean pop after 6200 - up jetting, plugs look good.

Possible solenoid change - this was brand new

Cal-Track and gears. Car has 4:30's, I would like to see what the up jetting, slicks and trap time come out at before changing this, but may be in the future.

After chasing gremlins, came out to 12 flat
