2008 Stock, Predator & Corsa Catback Dyno's

[Tinman`]

I dyno'd my 2008 Bee with 1000 miles today stock, then with just the predator tune, and then with a Corsa Catback installed.
All in all we are looking at over $1600.00 in mods for the two.
The stock rwhp & tq pleased me, I'm impressed at the #'s right off the showroom floor!
Also, I had no way to lock up the converter, so you can probably add close to another 20/20 to the numbers.

Instead of my opinions (we all know what they say about those), I'd love to hear others, this way I feel I'll get much more beneficial feedback...
TIA

I'll try to answer any of your questions if you have any.

it looks like the predator helped a lot in the mid range.

For one, its a tuner so if you expected huge numbers from it then thats your first problem. It may not show up on the dyno, but I bet if you did a stock 1/4 mile run w/o Diablo and then one with it, you will see much improvements.

As far as Corsa, I have never been impressed with it. Shoulda went the full SLP I catback w/ headers and high flows...

You got hosed on the peak numbers but up the curve on the lower end you are doing decently. I know its disappointing because you focus on the peaks but your off-the-line performance should be noticeably better. Also the catback should settle in to the adaptives a little over time and pick something up. At least they do on the 5.7's. Hopefully the same is true with the 6.1's and you will get back some of what you handed off. That Corsa is also the Mopar SRT performance catback, FYI.

BTW - your dyno operator screwed you. That huge dip, that looks like someone flinched. Your number were solid to that point.

And youcan modify your fuel and spark with the hand held it does it in ranged from 0-3.8k 4-4.8k and 5-7k You can add I Think upto 20% fuel and 10* spark I think, I have never maxxed it out.

So before you start belly aching about the product try to understand it first.

If your in De, I would invite you to go talk to Josh or Bruce at HighHorse Performance in Newerk De. Good guys.

I was thinking along those lines as far as the corsa goes, I definitely need to give it time.
Now, to be fair, next weekend I'm going to do a dyno tune with the 8 second ESP button push and no diablo tune.
I'll bet money that the only real increase we are seeing here is due to the reduction in ESP.
So to be fair, I will be following up with just that!

Sounds like a good lead, I will look into that Robert.
As for the spark & fuel adjustments your speaking of, these must only be available if your modifying the stock tune.
I have yet to go there, this is stricktly a representation of the canned 93 octane tune.
If this is one of the flagship tunes, I'm not impressed ok....

[RobAGD]

Its a Canned tune, very basic adjustments to fuel/Spark and should make some shift feel adjustments if you select those QA paramerters.

And you can modify any of the tunes on there. Be it the 93 CAI or 91 Performace Tunes. You dont have to be just modifying the stock tune you can modify the can tunes as well.

Also not holding and turning off the esp will effect your numbers. Thats why you see that wave in your lines.

Here is an example of an SRT on the dyno with ESP off.



Thats smothing 5 if I am reading it right.

And like I said, you got ripped, that 3rd pull is a throw away unless they did another and it did the exact same thing.

I would thing the only read to see that kind of dip would be some knock going on and the computer pulled timing. Did you data log ?

No log was done.
But all of the pulls were free.
We have access to that dyno any day of the week.
The shop is in transition to be sold.
I'll try again either during the week or next weekend.
What you said about the canned tunes being abled to be modified, that is GREAT news!
I will take my laptop with the applications installed and hook up the predator to get detailed pulls.
It may take me more pulls than most, but it'll be worth it.
Now that I know the canned tunes can be modified I'll make the adjustments until I'm happy with what is best.
Some of the literature is lacking, so knowing what you have just told me helps a lot!
I bet my next post is much much better.
Thanks so much for your input, it is appreciated!

That reminds me of something I wanted to throw out there.
Have any of you experienced the ESP light and traction control lights staying on once disabled with the predator?
I didn't try it on a test drive, only while sitting in the driveway one day without going anywhere.
Those lights stayed on full time after I told the predator to turn off the ESP...

You will see much more gain after 6000 miles + the last run with the corsa is too lean I think since you have power drop between 4600-4800 you can fix this, just make a few adjustments.

[CVP33]

I agree with everyone's comments so far.

1) I don't believe Corsa quotes any performance gains from their exhaust, just better flow. Which is sales-speak for "we didn't make anymore power on the dyno." Magnaflow, with their mid-pipes and catback were quoting in the 12-18rwhp range as I recall.

2) The "canned tune" from Predator gives better throttle response, remaps your shifting algorythms and will improve your quarter mile times. Some of these don't convey to a dyno but will make your car faster.

3) As previously stated, the PCM will learn your tune and your driving habits and become faster. I still believe that there is some kind of "break-in" software baked into these cars. No one has been able to prove that yet, but these cars definitely "WAKE UP" after about 5-6,000 miles on the odometer. The tune also takes about 500 miles to be fully effective. Again adaptive software at work there.

I currently have the predator 93CAI tune, Magnaflow mid-pipes, JBA catback and aFe CAI. I can tell you that I've had traction breaks from just punching the throttle at 60mph on cold tires. Anything around 30mph and it gets dicey. I love it!

[PaCharger]

Yes the ESP, ABS lights stay on for me after I have the ESP turned off via the predator. The only time I do this is for the track....i kinda like the lights being on though...it alway reminds me to change the tune back after the track.

[Chrispy]

I have seen several Corsa dynos with ZERO difference in RWHP (+/- 1RWHP from stock)
Magnaflow and JBA gains power but also noise/drone.

I think if you played with the tune on the predator you might have picked up power.

What was your AF through the range on the pulls? How much mileage on the car?
Cheers

The dip you see in run three is probably knock retard. To get any really fair dyno results you have to datalog to ensure similar coolant temps, air temps, timing etc. You'll also need to monitor A/F. Put it back on the dyno with A/F. It's probably on the lean side if I had to guess.

My friend with a 300c SRT8 found a dyno shop that is pretty experienced with the diablo (on frods and cameros). His 300c srt8 had a magnaflow cat back and the mopar cai. He made 362 with no tune. With the diablo 91 cai tune made 356. The dyno shop tuner made several adjustments/dyno pulls and brought the car up to 401 rwhp/ 404 rwtq. Next we did my car (stock exhaust-K&N CAI). Stock I made 354 rwhp/351rwtq. After a few adjustments I made 390 rwhp/396 rwtq. Seemed the magnaflow was good for about 10hp between our cars.
