The current goal for the car is to be able run 7.0/11.0 index with the ability to run well in the 10's if I feel the need. Just a simple low boost/low rpm combo.
All I can say is stick with your original goal. You always end up wet trying to change horses in the middle of the stream. If the M1 intake is part of the current goal, then the affect on performance is irrelevant. If you are bracket racing then as long as your car performs well enough to stay in the desired bracket, then so what if it is slightly slower or faster?
I would not change the stall until you get the turbo installed and see where you are. Are you worried at all the IRS is going to hold up to 10 second abuse?
On pushing the car through the lights, have you thought about a 2 step (assuming it is legal for your class)? Another option is to get a window switch and 2 low rpm adjustable chips. Find out what is the highest, safe RPM you can use without pushing through the lights. Set one adjustable chip 100 RPM below the target RPM and set the second chip at the target RPM. put the chips in the window switch and hook it up to an LED you can see easily from the drivers seat. On the starting line, once you are staged, keep the LED lit and you should be good to go.
