well, i just bought a performance chip called PROBOOST for the intake sensor (AIT) and i installed it...but when i tried it out....my check engine came on and now my car bogs at 5 thousand instead of 7....anybody know? is it normal or is it boosting my car a little...?

 

I've never heard of PROBOOST anything before. Got any info on it? It's probably one of the things that fools the ECU into thinking the AIT is reading a colder temperature than it is, and adding more fuel....which doesn't do anything. I'd take it out.

 

well, i bought it from ebay...designed to boost up 20hp and 15torgue...saves gas...improves mph and so on.....fake?...it seems working thought but cannot tell...

 

Now... i'm not new here or anything, but i've seen those on eBay myself, and would personally never trust anything that stated it'd give me 20hp for $10-20...

Just seems like if that were even fathomably close to being a projection of how much an average horse cost, we'd all have 2second cards for an extra couple hundred bux.

 

you probably did more harm than good putting that POS on there.

 

Ya those things are wack, a buddy of mine got one for his vw golf and the engine light also come on. We took that shit off and hour later.

 

well, they said that it is 100% guarantee to not harm the car's computer and act as normal....i don't know...i hope it won't damage my car's computer or engine...

 

Untunable chips are all crap. Stay far away from them...
