Look for the "Lets see your fully tuned timing map".
Anyways, try retarding the timing in the 120 to 160 load and 5500 to 6000 rpm column. Try 6,7,8, or 6,8,8 just play around there to see what you get.

Your asking for more of an Antilag than a 2Step which is capable of being set by adjusting the timing vs. load that you see in a certain rpm range but if you'd ever come into that load at that low of an rpm it would just suck to drive.
I would not see this being necessary whatsoever....it wont make you go faster, it will just make you slip the tires easier.

you CAN change your boost for the 2 step... theres more to it than just adjusting load tables... or just setting the RPM higher...
please be advised that you are changing more than just 2 step settings when youre messing with the load to benefit from 2step...

2-Step cuts either ignition or fuel at a certain RPM to keep them within a certain range. While doing so it may in the process build small amounts of boost, the higher the RPM the 2 Step is at, the more boost it will build which is normally small, less than 5lbs but can be more. Simply because the higher the RPM the more air the engine is pumping. That is a 2-Step..if you're changing anything else then it is no longer and probably falls under the next category.
Anti-Lag varys but is fuel and/or ignition timing based. Drag antilag like what you may do with a flash presents using extra fuel with changes in timing to cause what simply comes to a simulated engine load. This in turn spools the turbo. Antilag is distinct, you can hear when it is being used because it sounds as though the car initially bogs and then builds upwards of 20-30-whatever you want (psi).
Try coming off the line with more than 10 or 20 lbs in a 900+ whp car....all it will do is spin, therefore you go slower...and if it does manage to hook for a second, thats just the second before it then unloads the weight that was keeping the front tires from spinning, and once they start spinning, so do the rear. This has been proven time and time again. Supras and such can get large amounts of boost from antilag before a launch because they're RWD and they don't have to worry about unloading the front tires. Are there exceptions to this, I'm sure that there are as there are exceptions to everything but this should be a general rule because the laymans thinking of just givin her some antilag will make you run faster times is incorrect.

Antilag is in noway near the same thing as a 2 Step and in a high horsepower AWD Manual car you want a 2 Step...Not antilag.

No 2 step and you'll get bad 60'.
Use 2 step and you'll get better 60'. Thats where I'm getting at. With the right tires at a prep'd track, you won't spin with 12psi off the line.

also, changing the timing in those maps would absolutely effect the rest of your driving, especially if you road race or autocross, since letting off the gas at 6k and then getting back in it would cause the car to unload then reload the engine, causing the map to read below the 2-step set rpm/load point then going thru it when hitting the gas again since the load will increase, it will cause knock if not watched closely
