Nice Jason!! Now we're tied I haven't taken the nannies off yet. It was a cool day though, I can feel the lag on more humid days for sure. I couldn't get under a 4.8 last week when it was about 80 outside.

Wait what, you are in the 4's with only a cold air intake?

Stock intake and air tube w/ a k&n drop in filter

Catless down pipe

LSD rear end swap

Jacfab big mouth 72mm TB and 3" charge pipe

And a 3/4 finished tune.

And my race wheels are on

I have to drive with the nannies off when I have the race wheels on because the tires are different heights from front to rear. Car freaks out with it on. It was about 70 this morning...

Oh BTW, when I check it on my log in hptuners, it says I did it in 4.04 seconds :wow:

Sorry, that post was to darknightkamaro. If he's in the 4's with a cold air intake that would be off the charts.

That's quite a large discrepancy. I never believed the timers in the cars to be too terribly accurate, but that's significantly different findings. Of course, the car will be 'off' if you've been fidgeting with the tire height calculations in the ECU.

Right, the speedometer was 7mph fast when I did that last one. I spent about an hour messing with the tune Sunday morning before the race. It's right in the money now... Plus I changed the tune 5 times at the track adding timing and changing the shift pressures trying to eliminate the trans slip when shifting... I just ran this with the current tune.


I bet if I Check it in hptuners it's a 4.0 or 3.9

Press and hold the TC off button for about 8 seconds

So I did 4 pulls from a dead stop, but I only did the 0-60 in the dash on the second one.

In my hpt log, these are the 0-60 times


The 4.4 on the dash is the 4.107 time in hpt

I'd recommend keeping Stabilitrak enabled. It does not interfere with acceleration until you pass the programmed figures for yaw. If you don't understand what that means.... It means it doesn't interfere until you're already sliding sideways and loss of control is imminent. If you're sliding sideways, you'd probably want the ECU to intervene.
