    If it was "cheap" to increase HP or torque then the manufacture would do it from the factory. Or better yet, if it was "cheap" and didn't ruin anything then they would already be doing it.

    The only real way to get more HP/torque is to install a supercharger or completely rebuild your engine with high performance internal parts like pistons, valves, cams, injectors, manifolds, heads, etc.

    I don't believe that the is anything you can buy off the shelf that is going to make significant difference.

    You're all entitled to my opinion on this.

    What you are missing is that there is no specific tune for a particular gas. The computer finds the tune for its self. It may take a couple tanks of gas for it to adjust accordingly but it will adjust. There is the possibility that they took the self adjustability away in favor of more consistancy, but for those people who have the years that state there is a difference, there will be a difference. Maybe not as high as they stated but it will ultimately have higher timing. These motors are new to me so anything I am saying is questionable, but having dealt with knock sensors and KR on Mazda motors for the past two years I have a very deep understanding of how systems like these work.

    I've run higher octane in my '05 Taco with 4.0 since I bought it...if you look closely at the statistics the engine was "detuned" in horsepower and torque after '05...We also have a '04 4-Runner w/ 4.0 that we run the higher octane in...

    To the OP, look, this is physics really, these trucks are heavy with an engine that IMHO is somewhat underpowered to begin with so yes, like you, I sought out more HP and torque. What I learned along the way is having to separate fact from fiction and marry it to reality. My truck with two dudes in it and a half-tank of gas comes in right about 5000lbs, that's ALOT of vehicle to get up and make boogie. So right there is reality, this ain't a sports car and it's not a V8, without an SC, it's not going to do 12 sec 1/4 miles. Then it's what do you want to do with that power? If the answer is to drive fast, then good luck when it comes to any sudden turns, get a sports car, you'll live longer. Me, I wanted to have enough on tap to get up to freeway speeds quickly, pass quickly and pull the occasional heavy trailer. The insurance is too fucking expensive to drive fast anyways. So after MUCH research and having run across a few bogus claims along the way, here's what I did, it's still a work in progress but so far it's made DEFINITE improvements:
    1. URD MAF Calibrator, this will salvage your gas mileage after you put on a Cold Air Intake like the 63 series K&N that I put on. Be prepared to solder onto the wiring harness behind your glove box, price $212.00 shipped.
    2. Cat back exhaust, three inch stainless steel, nice exhaust note, minimal gains but I think I will gain more when I put on the shorty headers and Y pipe. $800 or so.
    3. Be realistic, I dropped about 1400-1500 plus the hours to put everything on and I still have a ways to go. I don't want to spin the tires and I would rarely ever need to go 110, but when I do it gets me there quicker than stock.
    I will probably end up dropping around another grand+ to get the shorty headers and Y pipe bought and installed, at that point I will have gotten all of the available power out of that engine short of a SC. I put in the best plugs and change the oil every 3000K religiously with only synthetic oil. My philosophy is simple, make it as easy as possible for the engine to breathe and don't do anything that will possibly wreck it or piss off the ECU.
    Bottom line my truck hauls ass for a 5000 lb, six cylinder truck. Yeah, it was worth it. To any Taco owners that don't think (therfore don't have), that the CAI and cat-back exhaust add HP and torque, I will GLADLY race you for pink slips!:eek:

    There is always a base map that is programmed into the factory ECU. From there the ECU can make the necessary adjustments it needs to run at peak efficiency since every engine will run slightly different. If there was no base map at all the engine would not run because the ECU wouldn't know what to do with any fuel.

    How is a K&N damaging to an engine? It makes sense that a higher flowing filter will feed the engine more air than it could get through the stock paper filter(s) and cluttered ducting and baffles..?

    Im curious about more info

    Excellent post. I agree that some performance parts are just that.. Performance enhancing. They will cost you though. I did the K&N aircharger kit, and Ported and polished my throttle body and those alone I can feel a stronger pull 0-60 and stronger yet from 45-80. . It kinda runs out of poop after that. It is a heavy truck for about 250 crank Hp. Plus 32.5" AT tires are alot heavier and have more rolling resistance than radials. But Im happy with it. I plan on spending some $$ on a smoother Y-pipe, and larger diameter exhaust from there back. I want headers, but they are pretty expensive and will be much later in my Tacoma future. Have you looked into light weight flywheel, pulleys, or exchanging the fan running from the crank for an electric fan like flex-a-lite? All of these would in theory lessen the load on the engine, putting more power to the ground rather than getting those parts up and moving...? Anyhow, good honest write up

    You get what you pay for.. Just dont buy any BS ebay power chips or special fluids that claim increases HP. I used to have a throttle body spacer on my scion tC, sounded cool, but no noticeable increase in power or mpg.

    K&N filters do a shitty job of filtering and if you oil them you'll kill your MAF.

    The motor was not detuned, it has been basically the same motor since 05. The Society of Automotive Engineers (SAE) changed how the Hp and Torque was measured. The 245hp motor is still a 245hp motor, just measures differently at 236hp.
    On a chassis dyno, they would measure the same.

    There is always a base map, but without resetting your ECU by removing the positive lead from your battery for about ten minutes or resetting it with a scanning tool your computer will most likely not refer back to that map without something like ceaseless engine knock or overheating for a long period.

    Belt changes on KB cars is much easier but still a bitch. Go turbo, but don't buy a kit. Buy a nice mig welder and all the mild steel piping you will need. Even if you outsource the turbo headers and you buy a Procharger intercooler, the cost of the kit will be less than half if you weld up the piping yourself, even less than that if you do a single turbo. Nice head units are less than $1000, you could even find like a GT42R for $900.

    seems to me acdronin sure spends a lot of time and money
    trying to make a 4x4 go faster
    however
    he is really going to save money if his oil changes last 3000k miles

    so you went from an underpowered truck to a truck that "hauls ass" just by installing a intake filter, URD maf cal. and catback exhaust?
