Bigger turbos!!!! Lag VS Launch

My.car. takes a north east cell pattern when I let the clutch out. Have you traced your launch yet ? A bog will send it farther north than east and a spin will jump to higher rpms.
Factory two step settings work for me on ax and street type pavement , but be careful when it comes to the real deal.. vht and other track prep may cause adverse launch conditions.
I've built only a 1-2 more psi than stock safely , I'm not sure how fuel tuning plays a role yet in launch maps .
Keep us posted.

Here is an FP Red Evo I tuned and the customer asked for as much boost on the 2-step as I could get, though I suggested it was a bit much for a good launch. It ended up being too much for his launches to have reliable traction so it was adjusted to around 11-13psi I believe.

This was achieved by using negative timing at the 2-step RPM and extra fuel during RPM ramp-up (you can hear it as the turbo starts spooling, sounds like gargling for a second). This approach always works for me and I generally can get around 10-13psi@6k rpm on a 6262 or 35r. Like everyone mentioned, the transition from the peak boost at launch, down to the area your car will 'bog' at, then back up to your normal powerband as the engine load increases is very important. Everyone has their own tricks and techniques with launch maps so try a few different ideas and see what works best for your setup.

Once boost is built, it generally will retain itself to some degree. You dont want it TOO negative in the peak areas where you will begin to transition under a driving load or you may induce knock. My best advice is to work on the boost building area first, see where it maxes out in load, then try tapering the timing more positive at full boost and see if there is no loss in boost.
There is no 'one way' to get these maps to work for you. Just try it out and make small adjustments until you achieve your goal
