I'm a new member with a stock '13 Cruze LT 6-speed. It's the first vehicle I've ever owned made after 2010. So after having it a couple months and browsing this site often, I have a few questions about performance for other members. The throttle in my cruze feels like it has a computer virus. It feels as though someone put the computer's throttle response from an automatic vehicle into a manual transmission vehicle. It's primarily a problem during takeoff, because the lag interferes with the shift timing. Would a tune fix this? If not does anyone have any recomendations to give the throttle a mechanical feel?

I didn't know this was even possible.

The Cruze does have the smallest displacement engine of any I've ever driven. But NOT the least amount of power stock. That honor belongs to my 1991 Ford Escort. That motor had 88 HP at the crank!

Welcome Aboard!(y)

Turbo lag FTW!

A tune is definitly a step in the right direction, but first start using at least mid grade fuel.

馃う鈥嶁檪锔 Great. This is also the first turbo car I've owned, so thanks for the clarification guys. I have noticed a slight improvement in power with 91 octane. I plan on using my cruze to tow a small trailer across the US in about 6 months. I'd like to improve it's performance prior to that. My planned performance mods are a K&N intake, Siemens Deka 60lb injectors, then a BNR tune. I'd like to improve the braking before the trip, but I'm not sure on what upgrades to make. Any advice is much appreciated.

In order my other vehicles have been 91 Volvo 740, 87 Volvo 740, 03 Toyota Corolla, and a 91 Nissan Stanza. I didn't reallize the lag I'd experienced in newer vehicles was from poor pressures in the shitty little turbos. To me it felt similar to the computerized throttle pedal thresholds in automatic vehicles.

The intake is worth little in performance, just sound and the same goes for aftermarket exhausts, assuming you stay legal.

GM makes the throttle delay a sizable one to save fuel.could also be a heat soaked engine running 87 vs premium so engine pulls timing to stay safe. Try premium and see if it helps, for best results a tune will take care of lazy responses and pick up some
Power. This is all assuming your engine is in proper condition and maintenance has been kept up with.

Wow. That a substantial technology jump. Drive by wire throttle systems do no behave in the same way that mechanical ones do. And from you list, it looks like the Cruze the first drive by wire throttle vehicle that you've owned. You'll get used to it. Especially since mechanical throttle systems aren't coming back in vehicles.

This is very true. The stock designs of the intake and exhaust are very good. But I love sure the sounds my she makes. 馃槈

I wouldn't expect to notice much of anything from the intake alone. I thought it would improve tuning results better than with just the stock airbox though. Thanks for the tip on the Buick rotors, and the coil pack.

This lag is not something I'd like to get used to, I'd prefer to eliminate it as much as possible guys, thanks for the tips. Can anyone point me to a thread comparing tuning options? Trifecta doesn't remove the 112mph speed limiter, so they're out.

BNR, ZZP, Vermont Tuning, or you can tune yourself using HP tuners.

I'm not sure there is a tread with comparisons?

I wouldn't take your Cruze over 112 MPH without V or Z rated tires. I worked for Goodyear for 10 years and I've seen some bad **** happen.

Sorry but that鈥檚 a pretty stupid reason to not get a tune from them. You want no artificial lag well a tune will do, and trifecta makes good ones. You could try badnewsracing but there aren鈥檛 as many tune options for the Cruze as there are for a LS.

I was thinking it. But I wanted to be nice.

You tune for your reasons, I'll tune for mine. I wouldn't expect nearly as many options as with an LS, but I'll work with what I can get.

I think it's pretty stupid that trifecta won't remove the speed limiter for paying customers. I understand the responsibility issue, but I also refuse to have my vehicle's speed limited to 112mph. I seldom drive as fast as the car can go (like almost never) but I do need that to be an option in my vehicle, and I won't stand for a 112mph governor, when I've set the cruise control on my grandpa's old 2012 Prius to 116mph.

I appreciate the concern for blowouts so I'll adjust my tire ratings accordingly, but I just bought tires so I'll let them wear for awhile.
