Receipt Text Font Document Paper

I went to the track for the first time this summer. Best time was a 16.3 @ 84.7mph I think that's a pretty good time for a full tank of gas. CAI installed and a down pipe and mid pipe. I ran the car stock last summer and my best time was a 17.1 @ 80.1mph

Not bad, and you know, I'm tempted to make a dedicated 1.4 mile times thread similar to that on the Sonic forums. I'm just not sure that there are enough Cruzes out there that are dragging their rides to warrant a dedicated thread.

I think the difference is the Cruze has less performance potential than the sonic. We can pretty much estimate already the times you will get with an Automatic 1.4T Cruze.

Here is the table:

Stock (138 hp): 16.5-17.0
Intake / Small mods (140-150 hp)- 16.0-16.5
Stage 1 Vermont / Trifecta Tune (170-180 hp) - 15.5-16.0
Stage 2 Vermont / Trifecta Tune (e85 or 100 octane) (180-190 hp) - 15.0-15.5
Vermont w/ Water Meth + Aftermarket Turbo (unknown hp) - 14.5-15.0

Note: Intake and small mods do NOT stack when used with a tune.

So is there any reason to do both?
From a performance standpoint, no.

However, the intake does help the power response in "Eco" mode of the trifecta tune (power is roughly equivalent to stock). You won't pick up any HP in "performance" mode, because of the way the tune works. It is a torque based controller. The only thing that will exceed the commanded torque is the input given to the ECU on the program.

The intake is mainly for looks and sound, honestly.

Absolutely most mods dont really stack in power over a good tune.A lot of people seem to miss the point.Plus some intakes even tend to run on unhood air.Not a good recipe for adding power.

First let me say I love my cruze.It was bought as an everyday driver and gas saver,which it is.What it is not is a fast car.I have a 98 escort that i'm pretty sure would beat my cruze and even with the tune it's still kinda slow.I thought hard about the trivecta tune but decided it didn't make enough of a difference to risk losing the warranty.If I had the auto trans I would get it for the help it gives the tranny but I have the manual 6speed.

My Trifecta tune chops 0.8 to 1.0 seconds off my 0.60 times. Tune in eco mode that's similar power-wise to the stock tune: 8.8 seconds 0-60. Tune in sport mode that bumps up the power by a good bit: 8.0 seconds 0-60. Those times were generated by my ScanGauge II in Performance mode. I've also checked my car's speed sensor against my Garmin GPS and my phone's GPS. It's dead on. Knocking 8/10 of a second off the 0-60 time is pretty darned good for $350 and 10 minutes spent re-flashing.

A Vermont or Trifecta tune does make a big difference.Your looking at a average of 30hp and 30lbTQ increase.And depending on 91 or 93 octane those numbers can go as high as 40hp/50tq.Also in normal driveing conditions there is no added stress on the engine.Unless the car is being driven hard.In others words its all about the drivers input for TQ request.And if you request added TQ threw medium to heavy throttle input the tunes added power is very noticeable

I definitely dont feel like i got those kind of gains from my budget tune.

It seems the Budget tune is some what reduced power from the premium tune.I think some of it has to do with it being smart octane based.To me a tune should be only for 91 and preferably 93 octane for a max power increase.But some people are interested in lower octane tunes.You can increase the TQ up to close to 180lb flywheel on 87.But it will drop off fast on the lower octane

To bad you could not data log and have someone view the GM Torque PID numbers.Its Flywheel out put for HP and TQ and is also fairly accurate
