Stuck in the 13s

[Chiefish]

I have a pretty comparable car to yours, all I have done is to install a Vararam intake, flowmaster cat back, and a JRE tune. If you take a look at this thread I have going its a history of my car at the track, The first runs are with the Vararam and exhaust installed, the next day I went was right after I did the JRE tune to it. I broke into the 12s on my first run that day after the tune. http://www.camaro5.com/forums/showthread.php?t=216440

this next post has links to videos of me running down the track to coincide with the second set of timeslips in the first posts.

I would think if youre running with headers and anything more then I am you should be in the 12s easy.

[MudderFinger]

back when I had just Full exhaust, CAI, and JRE tune, I ran 12.80 and a 12.92 against a strong headwind, so maybe it the Track DA was high. That run was on stock tires@25lbs.

Last time I checked I am still human!

I can make mistakes.

But Not given the Opportunity to correct any mistakes is just Unfair and does not make my tunes JUNK!

I am surprised at this remark since I have never left anyone hanging, I always answer emails, phone calls, and PMs.

But based on 9pm last night (DA 2606 ft) for Famosa Dragstrip.

Your 13.4 @ 105 mph would be a 12.9 @ 108 on an excellent track day (0 density altitude).
That's a little off the pace from where you would like to be with your mods.

I checked the DA for 6-29-12 and 7-28-12 both at 9:54PM(closest to 9:30PM) and both were around 2200.

In those conditions, he should expect to run 12.9s @ 108 mph (DA corrected - 12.5s @ 111 mph).

Yeh, something seems to be wrong.

That's what I found also.

.1 improvement in the 60" will equate to .2 in the 1/4.

There is more to a tune than just an ET improvement. A tune can feel much(light years) better even though it only improves by .1.

Been running in "s" every time, but it seems to take a few passes for the computer to learn that it's time to go fast. I drive in "m" every time I take the car out of the garage, which may not be aiding my times...

With 1 3/4" headers, 2.5" exhaust, ADM Race CAI and street tune(good tune, sorry had to poke the sleeping giant, lol j/k) I ran 12.5.

I'm not a 5th gen expert, but I'm running a lot better than your times and it was 3700 DA when I ran.

Maybe start with a fuel-related fuse pull. Does your current tune turn your fans on sooner? Were you idling in the lanes for a long time before you ran? Changing the fan setting can help you avoid slowing down from the coolant getting hot.

California tracks in general are slow but Famoso is actually the better of them just no so much so in the Summer months.

He needs to bring down his 60ft. somehow.

What differences did you notice between the 2 tunes? I'm looking to get a Dyno tune myself it just seems way easier and I get to know exactly what's being done to my car.

Crappy fuel down here is making the car pull tons of timing. Have yet to throw the 150 shot through it out of fear of destroying the seals. Waiting on a 3gal meth tank to arrive to plug that in and test our luck.

[Pro Stock John]

The old rule of thumb is you slow down 1 tenth and 1 mph for every 700 increase in DA.

That said, I rarely have run at 0 or negative DA, my 13.15 was reportedly on a 400 DA day.

That said, +1800 = slowing down 3 tenths, from 400 DA.

I'm thinking you should do the fuse pull, and avoid independent gas stations, and hit the track again. You want to run 86-89mph in the 1/8 at some point.

[Motion427]

Just to compare my run.
60ft was 2.017

at the 660ft
ET was 8.473 and mph was 84.79

At the 1320
13.009 at 109.05 mph

the car was bone stock,stock tires in mid sept,so the weather was pretty good.

I know I can buy a machine to mesure the DA,but isn't their a website that post the DA at certain tracks?

Not tryin to bash. Just an honest take on the tune I received. Not sayin all your stuff is junk. We corresponded a little via email, always got the feeling I was just one more noob to get off your plate, unless I was going to buy something. So bothering you any further would only lead to frustration on both sides. And without datalogging to back up my complaints, what could I say? Car feels slow?

Not wanting to lodge a complaint, already moved on to a different option anyway, so at this point the discussion is moot. Again, not tryin to bash. I know you make some killer machines, and mail out some good tunes as well I'm sure. Mine just wasn't.

And now we're way off topic.

Car pulls alot harder, shifts feel stronger & sound crisp now. No more black soot around the pipes is also nice. Acceleration is more immediate, there's no hesitation now. It just gets down to business.

Def the most noticeable power increase so far, by alot.

Wouldn't the recent tune eliminate the need for a fuse pull? Will def give it a shot if no.

I should also add that I neglected to lower my tire pressure all night on Friday. I'm thinking that may have helped. I've also heard that boosting the pressure in the front tires may also help? Decreased contact patch?

That would have been a good place to start

I would never want to get a Noob off my plate, Totally ridiculous statement.

I rely on you guys to keep my business going, and I am here to Help no matter how small or big your problem.

Not wanting to lodge a complaint, already moved on to a different option anyway, so at this point the discussion is moot. Again, not tryin to bash. I know you make some killer machines, and mail out some good tunes as well I'm sure. Mine just wasn't.

Why Not? I am here to take the good with the bad and find a solution.

I am always at a disadvantage in these discussions because I can't link your Screen name to your real name.

If you are not having traction issues then do not lower the rear tire pressure at all. Yes, you can increase tire pressure to the fronts as well. You may have to warm up the tires better and foot brake it to 2K and let her rip. You need to progressively foot bake higher and/or hit the pedal harder until you get some spin then back off slightly.

You should not have to do the fuse pull since you are changing tunes. When you reflash the ECM the addaptives reset.

Come down to SoCal and we can go to Irwindale for some 1/8 mile practice runs.

Buy a 50gal drum of race fuel and have it shipped down there.

Nitrous in Mexico is about $10 a lb but race gas is available at the track for a reasonable amount. A couple of people I know get together and buy some drums and get them shipped to the track who keep them there just for them.

[DandD]

Interesting thread, just as a comparison, I went to the track yesterday, the DA was 2300. I have LT headers, Vararam CAI, Pfadt trailing arms and toe rods, DSS axles and driveshaft, MT 265/40/18 street ETs, LPE 3.91 gears, and oh yeah a Jannetty tune. Yesterdays results 12.56 @ 112.......1.86 60'. So Ted knows how to tune one of these cars.

[Pro Stock John]

Your car is off, trust me. I ran in worse air and ran much quicker. If I was you I'd try the fuel fuse pull you have nothing to lose.

82 in the 1/8th is like stock in the summer.

Do yourself a favor and look at the L99 bolt-on time slips for cars going 12.4-12.8 and familiarize yourself with the incrementals.
