Am considering installing a chip in my 92. The local Corvette guru has told me that I would be wasting my money. Has anyone had any experience with a chip? Thanks!

I haven't had experience with a chip but I want to install one too. I can tell you what my GM mechanic told me. He said that you may not get much in the horsepower catagory but if you buy the right chip, that little bit of adjustment in the ignition curve that the chip makes will ad a little hp and torque. The other thing is that some chips change the shift point in autos. Don't know if you have an auto but I do and I think it shifts too early. For instance, it goes into overdrive at a lower speed/rpm than it should in myy opinion. My feeling on this early shifting is that this was an attempt by GM to conserve fuel. Some chips will make it shift at a higher rpm so you can stay in the power band. Mind you, this is all info that I got from my mechanic. This is not personal experience. I am doing research on chips right now and when I find out which is the most benificial, I will let you know.

Thanks for the info. FYI, I have an auto also and one of the problems with the quick shifting seems to be the ratio of the rearend. I had my VIN checked and also talked with the local Vette expert and most C4 automatics have the 2.59 rear gear! Of course, this does nothing for low-end performance. I will respond to you with more info as I get it.

Here's what I know. A chip install is best done in conjunction with a dyno session that establishes program parameters. Dynos give a good starting point for your original engine settings such as air/fuel, timing, spark, etc and should further outline your engine's potential. A chip without a dyno session may be too generic and may not take advantage of your vehicles capabilities. I recommend that instead of getting a chip, get a dyno session and a programmer. Programmers are more flexible and allow you to make lots of adjustments. Lastly, stay away from JET chips.

Actually I don't want to be too hard on JET Chips. I just don't think they are the best bang for the buck.

if you guys are looking around i have a 93 40th annv. auto. It would be great if you could give me a link or a starting price for one of these.

What about a chip in a 82?

According to all I've come across so far ,chips in 82 and 84 models are a waste of time unless you have major mods. i've got an 84 and i've been doing a lot of research before i start modding the engine. An 82 has 2:7? and 2:8? gears in the rear. 84's came w/3:07'sand 410 or so had the optional 3:31's. After that many C4 autos had 2:59's thru the late 80's. 1:6 to 1 roller rockers, and K&N and some gears, 3:23 or 3:42 for an 82, and a free flowing exhaust would help a lot w/out killing drivability.

Ok, I have done some research on various chips. The common theme on them all is that they say that the performance gains become evident only at full throttle. I won't be getting a chip because i don't drive my car at full throttle most of the time, if ever. I just don't think it's worth spending the money if all I will see is advantages at full throttle. maybe I haven't done enough research but as of now, this is what I have found.

Performance increace ? most likely not .. But 82, 84 and any other OBDI automatic trans vettes out there , the chips claim earlyer shift points ,and prevent to early TQ conv lock up that may benifet for using colder t-stat's..

I just got a Stage II and 170 Thermastat. From sales@tbichips.com is the email. I spoke with Brian. This cost me a hundred bucks. I have a 1985 everything is stock except for engine is 1988 instead of 1985. Brian helped me find my computer under passanger dash and told me what the box looked like. 6 x 8 Silver box. That was worth the hundred bucks.

This chip made a huge difference threw all RPM's. I tried the chip with out the Thermastat swap and got some slight pings at high RPMs because of high temp and cheap gas. My average temp was about 225.
Then I flushed radiator and installed the 170 thermastat. Drove to the gas station and filled up with some 93 OC and added some OC boost 6 points. Now fans kick on at about 178 something. My temp avg. is 181. It stayed that way on a 400 mile trip today 50 to 1++ plus miles per hr. speed.

Anyways this chip rocks. My Vette feels much more powerfull. Burns much rubber. I drove it today about 400mile trip on I-75 my avg. gas millage was up 3.6miles per gallon and I had my fuz buster, and plenty of cars that wanted to run very high speeds with me on the Interstate. I cant tell you what the new Top end on the car is but it seems way way faster top end than it was before.
I know there is a guy with a 1998-2000 Red Mustang I think, just north of Ocala that wishes his top end on his mustang was somewhere close to what ever it was.

Thank you TBICHIPS for this mod it made my day.

Hey if anyone knows how in the world to get a steering wheel off so I can put my new one on send me something.
