just bought an 88 iroc and he has a hyper chip in it. he also gave me the stock chip. it is running alil rough with the hyper in it and as far as i know they suck the big one. it has 400hp TPI and auto trans the 700 whatever. should I put the stock one in? and is it just plugh and play? I know carbs nada bout FI thnks

 

Neither. If it really has anywhere near 400 horsepower, neither chip is going to be anywhere close to what that motor needs.

 

I have to agree with Jim85IROC. A custom chip needs to be had to get that sucker to perform like it should.

 

 

Thats what I thought. where do u recomend I go? I personally hate most mechanics and always do the work on my cars myself. I have no idea about this stuff. but I do know computer programing and such. is this the prom chip burning that everyone talks about? I do have a good laptop thnks guys.

This is the chip that is in it.

and is it ok to drive it this way? which is better or should I not drive it and wait? I live in bergan county NJ if anyone knows anyone in the area that would make/have one? most speed shops do it? or is it something where u tell em what u got under tyhe hood parts ect., or do u ned to dyno it>? I sound like a retard that doenst know a thing about cars dont I? LOL. DOH! THNKS DUDES and DUDETTES Kev. L8tr

 

pls ne 1? I wanna use it this weekend. thnks

 

You can see if anyone in the NJ area can burn you one just to get your car on the road. I dont know of many shops that do it. Best bet right now is go put your old chip in and wait and learn about proms. If you know some CP, then this stuff shouldnt be a problem. Im starting to get into it now that i got my aldl scanner software and cable all hooked up... i just need a solid laptop instead of this huge a$$ desktop..

 

Thnks so do I just pop it in and let it run for a min or so?

 

I'm still running the stock chip with tf heads a decent cam and super ram and no problems. Although I know I am not getting the best results.

 

Doing the same thing here. I have a custom chip for an 89 but the adapter to my 85 harness isn't correct so I am running the stock 85 Vette chip with my 350..... Anyone got a wiring diagram for an 89 computer???? I've got an 85, 86, and 92 off this site, but no 89......

 

If you not into the DIY PROM stuff (yeah i know its blaspheme`) You could try Performance resource, to see if they can do a custom job, I only say them cause theyre local to NJ. Then there is Ed Wright. I hear he is one of the best. TPIS also does custom tuning, but will charge you an arm , a leg, and prolly your 1st born too. But if your up for the challenge, get the equipment and make you own.

The stock chip isnt much diffrent than the hypercrap, so they wont hurt the car, but it will hinder performance a lot.

 

COOL thnks guys as I said I have never tinkered with TPI B4. so Ill make some calls and let ya know.
