Pros/Cons of GMs new direct injection small blocks in 2014? Are these new direct injection engines a good thing or bad thing overall for us in regard to aftermarket performance and tuning? How will they differ from the current?

honostly, i think its a junk design..i see them in the new engines like the acadia, and terrain at work, and they hall have driveability issues because the fuel isnt spraying on the back of the valve, rather spraying directly into the combustion chamber. so all the carbon collects on the backs of the valve more and causes misfire issues.
we always have to de-carbon the engines.

Pro's ? They will push down the price of the LS3's and LS7's.
Con's? You will have to be one smart rich S.O.B to mod them.
Personally the New LT1 is longer over due. I think the cost of these engines upon release will encourage the LS3 market nicely.
I just hope the General decides to open up that pcm. So I can do my thing and bump up the HP.

I'm wondering if the direct injectors would be able to handle a wider range of power due to the high pressure. I don't tune, but would think with the higher psi, it would take a smaller increase in duty cycle/pulse width than a traditional injector to keep up with demand. So maybe able to go from 400 rwhp to 600 with only changing fuel pump.
