I was searching Ebay and happen to check this ad out. While searching the thousands of customer feedbacks replys, it almost makes a person wonder if it could possibly really work. I heard of taking a 4400 ohm resistor and wiring it to the comp. that it will change the air fuel mixture but never tried it. Wouldnt even know how to hook it up. Has any of you tried this on your truck or car?

I did this once..................not this brand, but similar..................big no no. It tapped into the MAF sensor. Took about 5 minutes to install, and it made the truck run worse. It almost seemed to be getting too much fuel. Never do it again.

NTM(not saying you will buy from this guy or anything), check out some of the spelling- This guy is screwing people left and right...

And these are just to name a few.....I know there's more

^i agree. although my truck ran pretty dang good. I had the Magnum. although I did get a touch worse MPGs but it acceled harder and responded better. I took it off when I got a real Tuner. If you want it ill ship it ya. PM me.

 

Junk, don't do it.

 

I also saw another called the jet chip but at a 240 doller price tag. This is more of a tuner chip offered by a manufactor. Also another have you tried it deal? I want to get alittle more umph out of my truck without having to part with my faithful inline or my retirement.

 

if you want it (which it might not work on your 91) just let me know, ill give it to ya for like 5 bucks+ like 5% for paypal if thats how you want to pay.

 

Ill have to look it up to see if it will be compatible, If so Ill will even pay the shipping cost. What engine size are you running?

 

5.4 hence why I dont think it will work.

 

whats your email? Ill send you an e-mail this guy on ebay sent me about the magnum.
