Seat of your pants testimony rules!!! :P

Gears multiplied by numerically higher gear ratios = more torque/performance. Math.

Oh, and I don't sell R&P kits or do installs for cash, either. I've got nothing to gain.

Superchips recalibates the fuel and spark tables across the rpm range.

This sums it up for the most part. The key being the engine tune/timing has to be set up to run higher octane or it is a waste of money.

I have for 3 years and there is a difference on premium when properly tuned for it.
The speedo limiter does make a difference on the highway for passing.
The rev limiter only raises the limit to redline, not to over rev.
Throttle response does not increase power just reduces throttle lag.
Superchips does offer Dyno charts for those interested.
If these tuners did not work they wouldn't be the most popular tuner for the 3.8L.

So, to the OP, it's your choice. I like my Superchips and won't run without it.
Yes, I have done my research and know how an ICE works.

Im glad you have run it for 3 years. How much HP and torque did you gain? Like I said I like to see proof before I drop $380 bucks on something a company "tests" I work in a testing lab and have seen cases where when a company tests their own product the numbers are tweaked and not actually what happens in real life.

as for the speedo limiter you go over 100 to pass someone? Thats a little fast I would think.

My jeeps rev limiter is already at redline as with most so why be able to change that?

Never said throttle response increases power.

As for dyno charts I said above I have seen companies fudge with those numbers. Where is the third party testing? Again I like real proof. Not marketing hearsay.

These tuners work because people dont do their research. If I paid $380 bucks to a company for something that should make my jeep faster it sure would seem faster to me, even though its probably not even noticeable.

So, my request still stands to anyone. I would love to see some third party results on said tuner before I throw even $100 at it.

In the old days on a manually timed engine we simply cranked the distributor to advance or retard the timing to suit the fuel we run. Even an 8.5:1 compression engine will show gains with premium fuel when tuned for it, specifically torque. High octane fuel burns slower and produces more power, (longer push, pushing the piston to the bottom of the stroke) but the engine has to be timed properly for the slower burn.
A good analogy would be the difference between modern gun powder and black powder.

Your two points here contradict themselves. Black powder burns really slow compared to modern gunpowder. So according to the first bold you should get more power out of regular, no?

You talk about gains but still do not site any information.

As to the link you posted, here is the quote your referring to:
Quote:
Modern engines are designed for some rather high air-fuel mix pressure, if the mix ignites before that pressure is reached the engine just won't work right, because ignition will happen at the wrong moment of the engine cycle. That's why only fuel with right "octane number" should be used for any engine - depending on how that engine is designed, otherwise it just won't work right. The vehicle manual usually specifies which "octane number" is right for that vehicle engine.

You cannot change the compression ratio without changing the internals, and that is what that article is talking about. Your engine should be detonating the fuel air mixture when it is as close to fully compressed as possible and that compression is the same no matter where your timing is at.

I am not being mean, I just do not like when people spew information that is not true. I know he is not superchips first customer. I bought their flashcal to correct for my 35's and the gears im getting in october.

This is a forum where you can share information and that is what im doing. I am providing a counterpoint to someone claiming gains, because I have done my research about it. Still cannot find any proof of any gains from anyone but Superchips themselves.

More cleaning. How come we cant delete threads anymore? Or am I missing something.

This clears up a lot for me, a newbie to Jeep.
My Former vehicle, F350 Super Duty 7.3 Diesel, Superchips increased Fuel mileage (5 MPG+) and sicp power. Now I know we are not comparing apples to apples, but Superchips has a solid history, Thinking about this for my next mod.

On The topic of increased octane, in some cases it is a waste, true. However, increases in timing advance will increase power and will require higher octane fuel. Now my experience has taught me this through trial and error in carbureted engines, not EFI, where all that is being done is timing changes, you can tune more power and and increased need for higher octane and it will not be wasted.

Just my 2 cents.

Not exactly what I said. I said being passed by Bimmers at 100.
On I-15 in San Diego at 0600 the average speed is 85, proven fact. Sometimes it's neccessary to get the heck out of the way.
This thread is going nowhere.
Peace out.

You provide no evidence that the Flashpaq doesn't work so what makes you right. I know it works. Try it for a couple months then come back here and tell us it doesn't work.

Nope. Still don't get this. Advance the timing and you're going to provide spark before the air/fuel mixture is compressed to the optimal pressure to provide clean burning and the most return on power. The only way I see this working is if the engine wasn't tuned properly to start.

I can appreciate that Superchips has been in business for a while, but I'd like the evidence presented to make sense logically and not be simply anecdotal.

I'll vote Bully Dog. From what I've seen, they have everything I'm looking for. As soon as the 2014 tunes are available I'm ordering one for the new Rubi. However, the Bully Dog offers a little more for Rubicon users than standard users (like allowing the driver to lock their axles in 2wd, 4hi, and 4lo). But, that's just my 2 cents. HP and torque aren't really factors for me though.

I have shown my proof with how engines actually operate. But here you go. How are you supposed to create a higher compression in the engine by changing the tuning? More fuel and air shoved in their will do it. But at that point you need to run a turbo or supercharger.
