I have owned my 2012 Cruze Eco (manual) for a little over a year now. I absolutely love the car save one problem... a HUGE Throttle response delay. The easiest way to describe this is if I'm in neutral (manual transmission) and I press on the gas, the car doesn't start to rev until what seems to be at minimum 1 second later. And when I am shifting the engine stays at the rpm I was at for an extended period of time after I let off the gas. By the time the car is ready to drop down the RPM I am frustrated. When I shift like a grandma the car works great. It seems like it is almost an assist for the driver. And I hope my description has been clear enough that I am not talking about turbo lag. How can I get this to go away??? Up until this point I have done quite a bit of research on the subject. It looks like it is definitely a known problem. I have a trifecta tune that should be here shortly. It seems like that was the best option to make the problem go away, not to mention get a little more hp. We shall see... I have also heard of a devise called sprint booster, but there has been mixed reviews on the device. Does anyone have the device on their car??? if so, does it work and do you have a manual? The last thing I have read is it might be caused by the spark plug gap being incorrect but it does not appear that anyone has actually tried and tested it... I know someone out there has to have an answer and I know every person who owns a cruze eco manual knows exactly what I am talking about. I always knew the car was not going to win any speed races, I just want the car to respond to ME instead of trying to assist me.
