17@60mph is different than 17@75mph.

No, it would seem GM does not have the problem wide spread. The Malibu is DI at 90,000 miles valves are clean as viewed by a borescope, just not an issue on the 2.0 LTG or it is very rare. The LT1 type engine has been direct injected since 2014 with no issues to speak of. This a bigger LT1 with an iron block. Used in the Corvette, Camaro, all the LT1 based trucks are DI. They have a good handle on it. 10 model years of DI V8s.So I'm not working to deflate the OP -- I'm just genuinely curious: how are these truck motors with GDI after some miles? Does GM call for walnut blasting or similar at certain intervals?
I also like the looks of the rig!

Thanks cline. I have seen the injector problem come up.Intake valve deposits don't seem to be an issue on LTx based engines. I replace a lot of Injectors though (Open Coil). The other issues I see are with AFM/DFM which the 6.6L L8T doesn't have.
Though I do see a few Variable Oil Pump Solenoid failures a year.....Generally over 150,000 miles.
