Having upgraded the factory injectors a few weekends ago with some spare V8 injectors I had from one of my other cars, I made the switch to Ethanol aka E85 mid last week and put the Cruze back on the dyno today for some initial testing.
The results… Awesome!
This is still stock turbo catback and dump pipe. Just Injectors & tune.
As can be seen in the above graph the factory tune has the injector duty cycle topping out before 5200rpm, my original tune adjusts the requested fuel injection to hold it out to the rev limiter.
