i bought something like that off of ebay for my 89 V6 firebird 8 years ago. i ended up paying $10 for a $.10 resistor. went into the AIT sensor or O2 sensor. i installed it and it did add power. maybe 10hp. but after about 2 months, could have been coinsidence but, my mass airflow sensor went. $300 for MAS and also he said my whole intake was dirty so he cleaned it. guy that owned it before me lived on a dirt road and probably didnt change the air filter for years. anyway, got it back and maybe 6 months later i burned an exhaust valve going 90mph on the interstate up a slight incline. temp gauge still read normal, but normal was 210. had the car overall for about 2 years. bought it with 99k and sold with 117k. those problems plus my tranny going(another $1100 for rebuild) and my steering column breaking(another $180). but the MAS and the burned exhaust valve could have been coinsidence but i did drive it pretty hard and also i was 17 and knew very little about cars and figured the more octane, the better so i would put 93 octane plus a bottle of octane boost, on occasion i added 2. so that also might have been a reason. but i wouldnt trust the sensor off of ebay. go ahead and try it, it will probably add power but not 50hp. and i never saw any mpg gains. stayed the same

 

but the guy has 100% positive feedback so it must be legit.

haha

good luck with the return......

EDIT: your only the second person to buy one haha major fail, and 5 out of 6 feedback are from the guy who makes these in his basement buying stuff

 

to put it back to stock you just take it out. its a resistor that apparently tell the computer you are getting colder air. as i stated above i bought one years ago for my 89 firebird. you basically take the AIT sensor out, put the resistor in a U shape and put in in the plug. but you tape it off and leave it out of the filter box. when you want it back to stock you take the resistor out and put the plug back in where it goes. i had to get my car inspected while i had it in so i took it out for inspection. from what i remember, it does absolutely nothing to the mpgs. and it does add power surprisingly. it took my firebird's 0-60 time from around 13 seconds to around 11. not kidding either. but the problems i had i cannot tell if it was from the resistor or the way i drove it and put all the octane in it. heck back then i thought the octane boost was NOS. never even knew octane boost existed. wow what a long way ive come...

 

glad to hear someone has actually tried one of these.
i actually purchased this one

we shall see if its any better. ide be willing to bet those of you that keep bashing these have never even purchased one. your so content on spend tons of money on your special tunes. if it works, cool. if not, big deal. 25 bucks down the drain.

thank you timmypstyle for actually putting in experience you had. i appreciate it

 

so you actually have a chevy express van??

and just cuz people with CUSTOM tunes didnt waste 25 bucks on one doesnt mean they work. 40mpg??? really

if you want something worth it then your gonna have to actually spend money on it. theres NO substitute for a custom tune

 

I kinda want to see what it did.. when will it arrive?

 

I dont think hes doing it to find alot of power.. I think he is just testing it out to see what it really does.

 

not a problem. but yeah dont even try to return it. those guys are your best friend when you buy it then never answer you when you have questions or concerns afterwards. if you dont like it, just throw it out. i know arohnd 10 yrs ago people would not buy them off of ebay. some figured out which resistors they were selling and bought them from somewhere like radioshack or somethign for about .10 per resistor. it really does work. my firebird seemed to have its own problems before i even got it too, i just made it worse with the octane boost and all that. by the way after my valve burned, i took it out but running on 5 cylinders soon became a headache, so i put it back in. it went back to the way it was with 6 before i bought the resistor. still drove it for a few months after that and nver had anything else happen to it. what else COULD happen to it? you also gotta look at my situation.
had about 110k when tranny went...around normal time for that tranny...intake was dirty which would have done something to the MAS...too much octane being used...drove it pretty hard...so all in all, the resistor could have had nothing to do with what went wrong. now they are making the covers for the resistors to make them look more professional. but open them up and all you see is the same resistor that i bought, just mine didnt have the cover.

 

no i dont have a chevy van. i just used the link as an example.

i know 40mpg is impossible. no dyno tune, canned tune, or $25 pos thing from ebay will get it.
it was purchased out of curiosity. seeing as very few people on here have bought one, i figured i'd give it a shot.

i know spending a lot of money on a real tune will be more beneficial than this.
but some of us on here dont have as big of pockets as others and expensive tunes arent always an option.

 

also i forgot, i am sure you looked at a few before buying. and i am also sure they all said something like "it makes the computer think it is getting the optimum 42 degree air to add the most power". well look at a few, they will most likely say the same sentence but with different temps. go ahead, try to ask one of them why theirs says 42 degrees is the optimum and the other says 50 is. see if you get a reply...

 

lol well in the event that my MAF goes out, that just gives me a good reason to upgrade it idk how it would have caused problems with the tranny if it changes air/fuel ratio. lol but we'll see. my tranny only has about 25K on it. its still pretty fresh.

im curious as to how much (if any) hp it will make. like real dyno numbers..

 

ltz400racer

it should be here in a few days.. not too sure though seeing as they dont ship on sunday and monday is presidents day.
im gonna guess tuesday of next week at the latest

 

the stock MAF is plenty until you add forced induction

 

This is precisely why you should avoid this route - if you are not cafeful, you could end up with fouled cats, or worse, a peckered engine.

Running a sophisticated engine control managment system like Ford's EECIV and EECV without ALL the sensors active & accurately functioning, denies such a system's ability to stay within known SAFE limits regardless of the ambient conditions, state of tune, component wear & aging, fuel variations. etc, etc.

With no 'deep' pockets, what are you gonna do if repairs are needed? Does that not sound like a non-sequitur to you?

One guy's results, with NO empirical data of any sort save his 'butt', on a completely different platform, is not a reasonable basis on which to proceed.

At least call up a tuner or two to discuss - perhaps they can talk some sense into ya! We sure can't apparently ..

NCSU - time fer you to tell me to let go again, buddy

 

Guys, there are some people that just refuse to be helped. They have to learn the hard way. Look at it this way, he will have something to laugh about and tell his kids someday. When they are about to do something dumb, and they say, "here, hold my beer and watch this", he can say, "hey, I once bought this diode........"
