Hey guys.. This is my first post here.. I was searching ebay for stuf 2 add to my monte carlo.. it is a 1995 ls. and i seen a computer chip that adds like hp and gas milage. I was wonderign if these thigns are 4 real and if anybody else has installed one.. I also would like to know if anybody knows of a legit computer chipo. cause i see alot of things that say add 150 hp and 50 gas milage..

Thanks for thehelp guys

 

99.9% of the stuff on ebay for cars is a lie

 

So you are saying there are no such things as these "chips"

 

The chips that advertise 150 HP and 50 MPG most of the time are a load of crap. The chip they send you won't help you one bit. Some of them actually perform worse than stock.

People spend a ton of money to gain that kind of horsepower. Superchargers, turbos, intake systems, exhaust systems, NOS, performance ignition systems, pulleys, etc...

Ifpeople could simply take a car that makes 250 horsepower stock, and make it 400 HP with just a chip change, there wouldn't be anybody buying the stuff I mentioned in the last sentence.

There are legitimate chips and PCM tuners out there, but they're not going to guarantee gains like that.

 

my advice is to run for the hills...

 

i know theyre fake... thats why i was asking if there are actually legit ones.. does anybody know what the good ones are called???

Thanks

 

Re-flashed Powertrain Control Module.

You either take yours out and send it in to have it re-flashed and it will be sent back to you ... or, you trade yours for one already done and hand-over your PCM as a core deposit.

 

Have you ever got the this done?
if so does it cost alot?

 

u can do as rick said or u can buy a programmer and reprogram it urself...as for sending it out check out zzperformance.com

 

One thing I think you guys are missing is he has a 95 LS, which would have that BS obd "1.5" pcm, which means any tuning he has is going to be pretty different from the obd2 guys on here. I dunno if anyone even sells retuned chips for them (I thought they used a chip, but I could be wrong).
