Stick with TBI or convert to OBD2 (Vortec/CSFI)

[Daveo91]

The 16197427 can operate 8 injectors when the 16197427 is converted to MPFI mode.

This is great news, Dave. Thanks much for the info and the zip file, lots of good info. I think I may go ahead and get a '7427 now since I can start out with all my TBI stuff and eventually switch over to the vortec.
