has anybody ever used one of these? is it worth the 300dollars.

 

imho,no and no!

 

why not? have you tried it

 

NO,i havent tried it.However,my Bosch unit works just fine for me at a fraction of the price.If i had 300 bucks to blow it would be on something i was sure would help my car and not a snake oil or gimmick.just saying.If you gotta have it let us know how much of a gain it gives you.
Why do you want it/what are you expecting it to do?did you research it any?

 

I bought one when it first came out and it was a total POS. Just made my car run like crap. I returned it and it also fit the air cleaner very poorly. It's junk. I was hoping it would be a good product but it was a real disappointment.

 

I have seen them on other cars, worthless crap! IMHO

 

You'd be better off saving that money and buying an aftermarket intake with runners and slapping on some headers... you will see at the least 30HP, that's if you also upgrade your CAT if equipped with a Hi Flow...

 

not too happy with mine.first one took a crap after a week.second one intermittently takes a crap.comes w/NO instructions on how to adj. .....just trial and error.i even e mailed for tech support...no reply.buy an adj. fuel regulator instead!less hassle and more or less same flexibility and end result.

 

i have everything else just thought it might be a nice mod thanks guys

 

No offense,but you have everything else and had to ask about it.just saying.I by far dont have everything else and still figured out it was snake oil.A little research can go a long way.

 

lol your right im mean as far as bolt ons go. and what is snake oil i dont understand this term.

 

Like WAY back in the day before the FDA when someone could put a label on a bottle and call it a cure all without any proof of what was actually in the bottle.A gimmick or a bunch of BS.I mean a bottle full of opium would prolly make anybody feel better lol.

 

My experience: I bought one and ended up returning it, then getting a rebuilt from Shucks for almost half the price. The rebuilt works very well. The granetelli one kept causing the check Engine light to come on and ran like crap.
