 The 3800 uses a waste spark ignition system where two cylinders each share one coil. Because of this your coil options are a bit limited unless you want to perform surgery on your ignition control module. The 3800 uses a waste spark ignition system where two cylinders each share one coil.

 +The factory ignition system is actually very reliable and quite good for higher horsepower builds according to most people. Typically though spark plug gaps will need to be tightend pretty significantly once you use a turbocharger. Most will gap the plugs down to around 0.025" instead of the factory 0.060".\\

 +You will know if you need to decrease your plug gap if you start misfiring under boost and everything else looks okay. It's a pretty common issue.

 +Way above what I want to try to explain right now, but basically it's running 2 ICMs in parrallel to output more power to the coils.

-The only+There is one aftermarket ignition controller that is well-known. This is the MSD 62152 DIS-4 Ignition Controller.\\ 
 +This replaces the factory ICM and will also require an adapter to mount and use the factory coils. This allows you to use a 2-step launch control.

 + 
 +Amazon reviews of this have been pretty mixed though and it is pretty expensive with a price tag of $700 for the box alone. 
 + 
 +You would need the MSD 8870 coil interface module for all 3 coils as well and that could be an extra $150.
  
 ===== Launch Control ===== ===== Launch Control =====
 +
 +There is a device called the "N2MB WOT Box" that will allow you to set up a 2-step launch control and no-lift shifting. It basically cuts power to the ignition control module to kill spark at a set rpm or during shifts.\\
 +You can find these from most vendors and will cost around $200
