My '02 T4R is a real dog on the road. Book says 184 hp, but it drives more like it has 50 hp. A specialty shop in Albuquerque, NM told me a couple of years ago that they'd love to sell me a chip, but there was "no effective chip" for Toyotas.
The shop in Santa Fe that tuned it up at that time said everything looked good, compression was great. At that time I had extensive maintenance done, including timing belt, water pump, oil seals, etc. No change.
Now, for the 1st time, I hear about the G Force chip and read their website. Is it possible something that works is available now ?? I'll watch this thread with great interest.
It's so bad that I'm considering selling the car - it's tiring to drive it. In rolling - not mountainous - country, it's constantly up and down shifting and screaming the engine - and still barely holds the speed limit. Thanks

??? lol... what does that mean? are you concurring that there is no slot for a chip. that your only option is to send in the computer?
I would also concur with RonMaiden that the only way to get more HP from the intake other than a CAI etc. is to do forced air/fuel, either a Supercharger/Turbocharger or 7th injector with or without NOS...
all of which I have seen done on a 3rd gen.

get a trueflow cold air intake and any other after market high flow muffler, and buy premium gas that will solve your probelms.

yeah, those things would be secondary on my list, it sounds like the poster has some other issues,
when were the spark plugs/wires last changed? have you run some fuel injector cleaner (ie. 44k by BG) thru it lately? how about cleaning the MAF??
if those dont work, how about a compression test to see if you have any blown/leaky seals
what size tires you running on what gears?
if all turn out to be good, then try the CAI and the aftermarket exhaust,
theres a ton of reasons your 4runner could be running slow but also know that its not a regular or common thing.

yes and no,
no in that you need an electronic turbo, but yes in that basically its just a high speed fan and its waaay cheaper...
my buddy rigged one up the other day with the 7th injector and beat an Audi A6. hes also now faster than my other friend with a 2002 supercharged 4runner.
the cool thing is that he has it tapped into his fuel line and the nos so he can either shoot nos or just extra fuel with the switch panel he put under his stereo...
the guys is ridiculously talented at stuff like this...
This could be a little involved. When I bought the car 2½ years ago, I planned to tow a small 16' boat with it, so took it into a shop to have a 96 plate trans oil cooler installed and, since car was new to me, had them change all fluids front to back, install a new timing belt and generally check it out.
They called the next day and asked me to come in. When I did, they showed me residue from a leaking water pump and recommended changing it, since they had it partly torn down anyway. Of course, I said go ahead. Then they recommended cam oil seals, etc., etc. I know they were strongly selling me up, but then again, I've been a mechanic most of my life and have a LOT of experience with distributor/carburettor engines.
Each thing they said was reasonable and sensible and tho' they were highly recommended by several people, I didn't like their attitude toward me personally which made it hard to OK all this. Since I didn't feel I had much choice and their recommendations Were reasonable, I gave a go-ahead and they went thru it - spark plugs, wires and all. Cost me over $2,000.00 to get it back, but I knew all that was done. For the best, I think. In 2½ years/30,000 miles I've had no issues at all - except for the power thing. They swore all was perfect.
Power is so poor, I gave up trying to tow the boat on the highway. It just can't do it.
I'm not familiar with the all electronic ignition/injection systems, but I will say that if this thing had a distributor I would guarantee that the timing was not advanced enuf. I still have my old timing light and dwell meter, but apparently can't use them on this engine. It gets just 18 mpg on highway - got 21 when I 1st got it - so I'd say it's getting plenty of gas, just not using it properly.
Is there a way to advance timing on these engines ?? I'd swear that's the problem, but am told it runs off a crank sensor and is computer controlled and non-adjustable.
Sorry to be so long winded, but this is a major thing to me. Hope someone has some answers. Thanks

I'll try again for a reply......... On other, older engines, I've seen huge differences in power with a simple timing adjustment. Is there a similar adjustment that can be made on these cars ?? Mine is an '02. Thanks
