well i run the calmini 3" suspen. lift and 30's  i still drive around town and comute to college everyday, but i do lack in the power catergory... im really puzzeld now, see ive done, long tube header, high flow cat, 2" full spin tech exhaust, cold air intake, iridium spark plugs and preformance radiator, but still have pwer issues. my egr is flasheing again so i wonder if thats the cause, or  maybe mines just gut less.  please if any idea of mechanical or reson let me KNOW!!!      oh ya with all those mods im getting 20mpg  shifting at 2900rmp.  city or highway it doesnt matter..  is that really bad?

help me before i sell this thing.

Aside from your check engine light, which I would get diagnosed asap, your rig sounds about normal. A lifted Trackick with big tires and no gearing change is actually pretty good at 20mpg. As far as your power issues, All Trackicks are dogs to begin with. You didn't say if yours is an 8 or 16v engine. The 16 is a bit more powerful. Maybe gearing? Turbo?

    Front and rear gears wpuld be the best solution.It will gwt your engine back in it's optimal power range,and should improve mileage quite a bit.

Shifting at 2900 is a bit low.  You should shift at 3900 RPM.  The G13 and G16 are not like US engines - they like to rev high in order to get good performance.

As others have said, Ring and pinion gears with a bigger ratio would help except that, depending on what engine/transmission combo is in your Tracker or Sidekick, you may have the highest OEM R&P ratio available.

Try running the engine at higher RPMs.  They (1.6 engines at least) typically develop more power starting at 3600 RPM.  They redline at 6000.  I never run mine over 4200 RPM mostly as a daily driver. 

Hope that this helps

Wow.  By the subject line, I thought maybe the sky was falling.  Or a wolf was eating our sheep.  Or something catastrophic like that.
 
But, no.  Someone running 30s with stock gearing is getting lousy mileage.  Oooo!  Stop the presses!
 

Show's over, folks.  Move along.  There's nothing to see here.

I have a simmilar set up. I have a calmini 2in. with 235s spintech 2in. exhaust. disconnect the battery so the computer can get a good new read, it helps. After my tune up I am very close to stock power. For the 3 in. lift I would deffinently do a gear swap, it shouldnt be to expensive!!! Good luck!!!

ya i am running 5:12's i beleive its a 94 16v 5speed, so wut gears should i go with most are discontinued right?  And  so if i shift at 3600rpm range ill get better gas mileage?   hows that work

so if i shift at 3600rpm range ill get better gas mileage?   hows that work

Because the engine will be bogging down less and producing much more power.

k ill try it, but how much did the tune up cost kickscrawler91 what all did they do adjust the vavles, or wut?

I do believe that your MPG is a little low. I'm lifted with steel wheels and 31" MT's, and I get 25-26 MPG. I think the advice you've gotten is good though. Reving the engine a little more for the shift points should help you out some.

I worked out what your problem most likely is.

You're not running the Nology spark plug wires.  According to a lot of guys on the board, they make a world of difference.

I'll let everyone else try them before i think about getting them.

where do you find these wires, autozone, shucks, or internet???

You're not running the Nology spark plug wires.

ok, mikey ... time to get an alter-ego of "sarcasm_mike" ...

Show's over, folks.  Move along.  There's nothing to see here.

I did feel a bit like a rube at the carnival when I actually read the contents of this post...

It IS bad form to cry wolf to get people to read your posts. Someday yo'll REALLY HAVE a big problem and nobody's gonna respond to your posts because of your previous attempts to get our attention.

Please be more descriptive in and less DECLARATIVE your subject line...   

#1 - are you SURE that's the gas mileage you're getting? Do you know if your speedo has been corrected to match your larger tires? Are you adjusting for that?

30" tires will reduce your gas mileage, but it shouldn't be killing it like that.

* Your #1 problem is your shifting WAY too early. Every engine has an RPM range within which it's running most efficiently. In 1.3 and 1.6L Suzuki engines, that range BEGINS in the low 3000 - so you're shifting JUST when the engine is starting to be efficient.
* The mods you did will FURTHER compound your problem with shifting too early. At least 3 of your mods HURT low RPM power / efficiency, but help you GAIN mid & high RPM power / efficiency.
* It also depends on how QUICKLY you're trying to get to those shifts. If you're depressed more than 1/3 of the gas pedal during accelleration, you're going to suck down more gas (acceleration is the #1 driver controllable factor of gas mileage).
* Are you driving in heavy traffic, or up & down a lot of hills?
* Are you keeping up with your maintainance schedule (oil changes, plugs, wires, valve adjustments etc)?
* How "fresh" is your engine? Is it high-miles? Was the person before you hard on the engine (by bogging it down by shifting too early, or accelerating too fast, or carrying too much weight  )?
* What brand of tires? If you're running a heavy bias-ply M/T tire, it could be heavier than a standard 30" tire, and rotational mass KILLS gas mileage / acceleration / breaking distance.
* If you want to play with additives to help improve gas mileage, visit bobistheoilguy.com
* Not sure about the iridum spark plugs either. "performance" parts usually do more to hurt a daily driver than help it out. NKGs seem to work best, and their cheap.
* Performance radiator? What the hell does that mean?
* What's a "Flashing EGR"? Are you talking about a flashing "check engine" light? If so - your engine could be running rich (kills MPG & destroys engines in a hurry).

There's no such thing as a high-performance & fuel efficient vehicle. They're one or the other. You'll have to decide for yourself what's more important to you: Going fast, 4 wheeling, or fuel economy.
