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.

I have the tune and a sprint booster. The sprint booster alone helped with my throttle response. Now with the tune, I don't even notice it. I have 1.8 AT. The tune will give you that pep you need. You can try the sprint booster as it is a 30 day money back guaranteed. I also found mixed reviews but if you analyze the negative reviews they are individuals who are stating their opinion as a fact. They have never tried the product to past judgement. I figured what is the harm in trying it, if it has a guaranteed. Well lets put it this way - I kept it. Cheers.

There are a couple of mods that all help with the throttle response. This car pulls timing especially when hot outside. I got my car in July and it was dangerous on take off. I switched to 93 octane and that helped a lot. Others have remove the intake resonator and that is supposed to improve response. I have not, I only switched out the air filter with a K&N and that seemed to help a little. Gapping the plugs to at least the stock spec of .028 will help, mine were 024 to .025. That helps too. The Trifecta Tune will also help as more torque and comes on sooner down lower than stock.

Switching Octane made a very nice improvement I didn't notice much from bypassing the intake resonator but everything counts. I had inconsistency with my spark plug gaps. I have great start up and acceleration. I can accelerate with ease with my AC blasted which was huge before. I think the best bang for your buck bro is the the tune. It will change everything for you.

I wish there were more things I can do with the 1.8! I should have my SRI early next week.

I'd gap the spark plugs to 0.028" and see if that helps. You'll want the plugs gapped evenly with your Trifecta tune. Remember, the tune is 91+ octane only!!! And, datalog the tune before playing around with it! Give the car about 100 miles to adjust to the tune, then datalog it and reflash it if needed.

I don't have a throttle delay. When I step on the throttle the engine responds. Now if I'm at too low an RPM the car can't respond because there's not enough torque, but that's driver error. My engine is stock with the plugs at 0.035". I run 91 octane.

They are turds until the turbo spools. Embrace it or change it. I've learned not to pull out in front of anyone.
- My ECO 6M seems pretty quick especially in the lower gears, granted I have the tune, but 99% of my driving is in ECO mode. No fears here pulling out onto highway or passing.

Just got an updated tune yesterday, night and day difference. 2,000rpm has no lag. The second I lean into the gas in 6th at 70, it pulls. The tune is awesome, and the throttle response is amazing with the update.

Really didn't believe all the hype about a few thousandths making a difference.

So while my oil was draining I decided to regap my plugs. They were .026-.029 so I bumped them up to .032.

What a difference. I only took it for a short spin, probably a half mile there and back. It sure seems like that 2-4 second delay is gone from the initial take off.

I will know for sure while I'm bombing around for work in the ol' girl today.

For a gas mileage improvement I would of bought it but not for a hp gain. A very cheap mod I can live with.

Thanks.

Comments like this make me wonder what GM gave up when their lawyers told them to set the "official" plug gap at 0.028 instead of the original 0.033-0.035". Yes, there are tradeoffs in any engineered system, but when lawyers and accountants get involved everyone loses. Look at what happened to Pontiac after deLorean left.
