The intake combined with the spintech 9000 makes the jeep sound like a hoss.

 

What does the dyno reports show? Curious.

 

Probably like 0.5 hp increase. :P

 

Trying to compare it to the k&n. I think theirs is 8hp.

I wonder about the metal tube and heat. How is that?

 

you're just not going to see substantial power increases with any "HP" upgrades to a 4.0
I'd like the spectre intake for snorkel purposes, bad *** sound, and it's a shiny engine mod. If you're on a chase for HP you need to get a stroker

Dyno's don't lie. K&N is 8hp. Hypertech it, and gain another 13hp! Again, dyno report reflects so. That's 21hp. That's also 10% gain. Not bad in my book.

As for stroker, i'd do my home work. I did and passed. Too many reports saying after break in, the motor went south.

To each his own. It's your jeep. Wrench away.

That 8hp gain occurs over 4500 RPM...

 

Once again, as its been said so many times.. a hypertech does NOTHING for a 4.0 that was put in our xj's. Any changes made by a hypertech, edge programmer, superchip, whatever (as little as they may be) will be corrected by the computer within 100 miles or so. So you may see a small difference as soon as you put it on, but every bit of that will be corrected for within a small amount of time.


But as far as the CAI goes.. Having a 4 banger i notice every little power increase done to the motor, and with running 31's on the stock 4.10's, I could tell at least an 8hp difference with my homebrewed intake. However thats not even to be REALLY noticed on a 4.0 to be honest. Now should you go with a CAI, new catback, and say a bored throttle body.. you'd be able to tell a good bit of difference.

 

Nice! Thanks for link.

 

And you know this how? I guess their dyno reports lie then huh? I have ran Hypertech on 3 trucks in 7yrs. Surprised they haven't been sued for their lies and false dyno reports. You do know, they have been around before you were born right?

You saw the dyno reports on the TB right? Hint......ZERO gain. Cat backs, and CAI do have gains, AGAIN per dyno report.

Sorry, I would trust any dyno report over some young kid with his first car that "feels" his opinion is right.

 

So your jeeps gonna go fast? That's awesome man

 

Have you ran a hypertech on an xj? No one ever said hypertechs dont work on other vehicles, and in case you forgot, your "trucks" arent jeeps and they sure as hell dont come with a 4.0 running OBDI or OBDII do they? Didnt think so. Hypertechs work perfectly fine on a normally tuneable engine, which doesnt include the 4.0. Ever wonder why those who go into forced injection use a piggyback? Thats because you CAN NOT tune a 4.0.

And where is this dyno report on the Throttle body? If you actually knew what you were talking about, you would know that Throttle Body SPACERS do nothing. A bored throttle body is nowhere near the same thing there bud..
And once again please show me the dyno on the before after when you decide to actually run a hypertech yourself. I have PERSONALLY put a hypertech on an xj that a stupid friend of mine bought and the difference was minimal at best. The jeep reverted back to stock about half way through the week 3 different times until he finally realized he was stuck with a useless box to throw in the dash.

So this "kid's" feelings are based off FACTS and Personal experience. When you have some of either report back to us.

 

You can adjust/mod the 4.0 when it goes into open loop under acceleration. That is the only time you need to make any adjustments. You can change the MAP sensor value to richen or lean it. Superchips and Banks make a programmer. My supercharged 4.0 runs all stock ecu and injectors until boost when it goes into open loop and the 7th injector fires controlled by an Auxiliary Injector Controller and there are no CEL's and no ecu learning and cancelling anything out.
OBD I and OBD 2 are on all the cars and is nothing special or to be afraid of.

 

So, you're believing in a dyno report on a product from the products maker? Smart. Yeah, I'm sure the did gain 8hp. In a controlled environment on a properly tuned engine. If they even dyno'd a 4.0 at all. Do you really think they dyno every single vehicle they make an air filter for? I bet the math nerda just calculate the numbers, print out a false dyno, claim an 8hp increase, then steal your money and laugh.

 

You're running a piggyback along with 7th injector are you not bpas? Yes you can change the map sensor value.. with an adjustable map sensor.. Not with a programmer chip.
