Unichip Power enhancer - more power!

Avoid it like the plague since you'll never see those numbers;it simply can't work without adding more air and fuel and that can't work that way with just a chip.

Exactly! You need to either be turbo or supercharged to get any gains out of a chip.
 
I want to second all the comments here. You will never feel or see those numbers, if they actually occur. These "chip" solutions tinker with your ecu and mess with factory settings. Those settings, by the by, are designed by Toyota to take many, many factors into account. Balancing longevity with performance with environment. For gain you will NEVER notice, why mess with what Toyota developed.


Waste of money, and depending on how the chip "achieves" those gains in the combustion process, likely see a reduction in longevity in components.

Not worth it.

Edit: If you want to see a noticeable performance gain that doesn't cost you a cent? Find an old 2nd gen 4cl or v6, drive it for a day then go back to yours. That should make you happy. :)

Awesome, thank you very much for the responses guys! You saved me alot of time and money!:cheers:

I am gonna go and dyno my 4runner now that I have both the K&N aircharger and Gibson exhaust. I am just curious what it is sitting at now. Should be very interesting and I will definitely post the results.
 
I would stay away from any chip mod for any vehicle. I know of a lot of guys down here who have done the chip mods for their trucks(Dodges and Fords). They all wanted more power for towing. They got more power but after about two to three years their engines were shot.

Were they watching their EGT's? It always depends on who you go with. In that market (diesel) some don't limit injector control when temps get to hot.
 
There is always an exception. However, the take away is this... in general, ECU chip mods give at MOST a LITTLE increase and usually none; while at the same time they affect the factory ECU in such a way that it can have a negative impact on the longevity of the vehicle.

Stay away from it.
 
Not necessary, if you go with a safe tune and are aware of the engine abilities there's little to no effect on longevity, but it also means you have to watch it more closely as well and don't skimp on maintenance. I've seen quite a few 1gr's go past 100k and more with no problems and they boosting 10-11lbs on the 1gr. I installed a X1 in a XR with 130K+ on it and it ran MUCH better. He's still driving it and going racing on the 26th with me.
 
a chip is made to Lean out your engine (less fuel) problem is this will cause your engine to run hot causing more wear on it than normal. If a chip re-maps to add more fuel it does no good without better air flow. all you end up with is bad plugs and or a hot engine IMO

The thing to look at is the AFR (air fuel ratio) modern Toyota's come outta the factory running a little rich. in most cases they do lean it out if N/A boosted is another story (TRD flash is a little rich too) motor compression ratio, gas octane, spark advance, flame speed, plus lots more all come into play when selecting the best and safe AFR. It takes alot of R&D to do the fuel mapping, spark control, timing, etc if going with a more advance unit but the Maf cal follows the OEM tables and adjusts the AFR on reported conditions.

+1 Listen to the man.

This is true of most vehicles... they are typically tuned from the factory 'safe' with plenty of room for operating smoothly in extreme heat, crap gas, etc.

A tune from a reputable company is perfectly safe and will tap into that 'extra margin of error' usually by leaning out the fuel mappings and increasing the timing curves. The tune from most tuners typically requires premium fuel to prevent detonation although not always.

When I purchasd a custom tune for my Mustang, it really woke the car up.
