Looking for opinions on best approach when tuning at the strip. Assume the car has been modified to the extent that any previous information that you have gathered is invalid. i.e. new engine, gears, tires etc.

This is a carburated, leaf spring car with no power adders.

What is the best sequence?
1) Timing
2) Jetting
3) Launch RPM
4) Shift RPM
5) Tire pressure

I think I would be looking at jetting first with a "safe" timing set, once that is ok...then mess with the timing.
3 and 5 are kinda related.

agreed 3 and 5 are kinda related but one good bit of advice is to change one thing at a time so you'll know what helped (or god forbid hurt) the combo.

If possible I'd go with an Innovate wideband o2 sensor that allows you to datalog and examine then make changes based on that. If that's not possible I'd start with reading plugs and adjusting air fuel mixture until the car is consistent during day and nighttime hours. Meaning that you don't want it to run .5 sec quicker when eliminations start (if bracket racing).
