The 96-up Vortec engines (V6 & V8) are classified as central, sequential 
port injection.  They utilize both a cam and crank sensor as well as 
seperate fuel injectors connected to each poppet nozzle and operate in TRUE 
Sequential Fuel Injection mode.  The 1995-earlier Vortec V6 used a single 
injector hooked to 6 poppet nozzles, which classifies it as Central Port 
Injection (batch fire).

Tunercat (C.A.T.S.) has support for 1996-99 Vortec Trucks, as well as some 
OBD2 LS1 vehicles.  Support for 2000-up vortec trucks and other vehicles is 
coming soon.

I have the Tunercat vortec truck tuning software and have already tuned a 
couple vehicles with it.  If you need a custom tune, or help understanding 
the tunercat software (or maybe just want to know what it has to offer), 
feel free to contact me.
