That article overlooks one thing:
The Gen5 LT5 uses BOTH direct injection (into the combustion chamber during the 'squeeze' phase)
AND port fuel injection (into the intake port during the 'suck' phase which is actually under supercharger pressure).

can any of the stand alone ecm's even run DI and port at the same time yet? cause you really need both to make power. direct injection hardware is crazy expensive to run more fuel than stock. only way I could see a cost effective swap would be a junk yard 5.3Lt. leave the stock di stuff in place. add port injection for boost fuel and run it off something easier to tune like holley and be OK with its running kinda bad around town.
and from the article.
When going from DI to port injection, you can expect a drop in power of about 4 percent on pump gas, 8 percent on E85, and 12 percent on methanol. — Brian Tooley, Brian Tooley Racing
there's no way I'm dealing with the extra di headaches in a swap for 4 precent more power. these people are crazy.
