Launch control ok but not building boost
80% fuel cut @ 3250 +
60% spark cut @ 3250+
-10 deg timing trim @ 2750+
Still not building boost (yes i have cat but im not using for emission's)
yes i searched; if i missed a good thread let me know. it works and holds 3250 rpm but doesnt build boost.

There you go. For the record I think that method is way better than launching in boost because unless you're making teeny weeny power and/or have some serious traction-enhancing modifications done chances are you'll just light up the tires and actually be slower off the line.
Look at soviets vid (I can't see it at work now but pretty sure I remember it from way back): despite having sticky tires and launching in 2nd gear he still lays stripes like no tomorrow. The trick is to manage bog and spin, not have a ton of either.

And yet it is the answer you need. Maybe you should have asked that?
If you use spark cut launch control you will plug your cat and your car will not run. What part of this don't you understand? Launch control = dump unburnt fuel into the exhaust. Unburnt fuel in the exhaust = plugged up cat.
