anyone running a performance chip

I am not really sure how efficient they work or if they even give the upgrades they claim but I see a few that offer a 7mile per gallon increase...has anyone used any that they can recommend

 

No chip is going to give even close to a 7mpg increase, not on a Tacoma at least.

From my understanding tuners/chips don't really do anything on our trucks. I haven't had one personally though.

No dealings with them myself, but the general consensus around here is they do little to nothing in these engines, same for "cold air intakes."

 

A chip you say?

I smell kool-aid.

 

there is no such thing as a 'performance chip' that does any good

what you can do is try one, and waste money. Or get one that really does improve MPG but it does it by making you run super lean and your valves will burn up in 1000 miles, then you have engine damage. running critical lean you can get >480 miles a tank on a tacoma but engine will absolutely not last, and your whole exhaust system will be cherry red and might start a fire. (does this by faking a/f signals)

the ONLY 'performance chip' or 'reprogramming ecu' that actually works also involves thousands of dollars of engine work (new intake, injectors, cams, blower or turbo, ecu, headers)

in other words, race modifications.

If there were a 200 dollar or less modification that would actually increase MPG without interfering with engine management and emissions, toyota would already have built it in...adding even 1 more mpg on the advertising would sell more tacomas immediately.

summary: don't get suckered. you either spend 3 grand or more for a complete job, or just don't bother

 

I put a chip in an 87 corvette. Did absolutely nothing. Worst mod ever
