Default Proformance Chips

Guys, I would like to upgrade my proformance chip. Which one should I get? I was looking at Jet Stage 1, would this application work for my car? If so, which model number should I order?

The first thing to do for a performance chip is remove the Nitro Chip that you have:
http://cgi.ebay.com/ebaymotors/1991-...temZ8021425377
Which you paid almost $30 (probably more with shipping) and is nothing but a 25 cent
resistor in a box with two wires and doesn't add 20hp like they claim. It might be half a
horsepower at best. Possibly 5 for the first half hour, then it fixes itself.

Their claims are actually quite wrong and they clearly don't understand how the PCM'* in
these engines work. That 'chip' can't change the AFR for more than a few seconds
before the O2 sensor corrects it. It CAN increase timing slightly in a pre-OBD2 car without
a MAP sensor. But again, it'* worthless.

Your only PCM option is www.gmtuners.com and you better REALLY have a solid
understanding of shift points and power curves. A dyno run is a necessity for the info
you need to have a chip programmed.

Yes, please remove it. I have heard horror stories about the supposed HP chips blowing holes in pistons. Sorry man, but you got ripped.... bad. If you can, please return it. We need to put a stop to those kind of things.

With too much timing, yes blowing holes is possible, but very unlikely in a non-supercharged engine.

Default Proformance Chips

I actually had it on for about a year but, it was time for my inspection, so I took it off and I am leaving it off. Alright, truth be told. After you asked me 'what is a Nitro Chip' (Wilwren on my other post about exhaust systems) and when I told you, you did not say anything about it. I started feeling self-conscious, because before I bought it I remembered reading in the Techinfo how I should not buy chips off of ebay (but I did it anyway). I started doing a little more reading to see what you guys were doing. Then I started searching for a chip for my car. I found something at Proformancecenter.com, they have a JET Stage 1 Performance Chip model #19420. They say that this pro. Chip would work on my car.

Jet doesn't offer you a chip for your 94.

The 92'* can use this:
http://www.jetchip.com/products.asp?...&make=40#parts

Northstars and L36'* can use this:
http://www.jetchip.com/products.asp?pid=23394

92 and 93 non-supercharged and 93 supercharged:
http://www.jetchip.com/products.asp?pid=23393


That Proformance site you listed isn't even a real site. It'* an advertising search engine.

I have been using www.gmtuners.com . Ryan, the owner, is an awesome guy to deal with.
To get the most out of your chip with him, I would suggest the following.
First get a good scantool. Then, get comfortable with collecting data. Researching what is all means will help too. Once you see where your at in terms of fuel and timing it will be much easier to go from there. You will be able to see if any fueling adjustments need to be made and when advancing your timing you can make sure your not getting any knock.
Other things you can do are turn the fans on earlier, change TCC lockup speed, and some other things I can't remember.
You don't need to get on a dyno unless your planning on raising your shifts.
