Ok , I think everyone has heard of the superchips that you can get for the 2.8 that cost like 250 or somethinglike that.I was perusing Ebay and I came across these

Hot Hips 2.8 TBI

Of course the standard disclaimer that I have nothing to do with this item on here.Just asking some questions about it , and if it would work with the 3.4 or if it just works with a stock 2.8.Heres some copied stuff from the listing , no idea if its been programmed like the superchips or how it works exactly , but its waaaay cheaper than the 250 bucks.

This is a performance chip for the service number 1228062 ECU's used in S10 trucks, Blazers and Jimmy's and Isuzu Troopers manufactured between 1988 and 1992 with the 2.8L V6. I have this chip for either the 5spd or automatic transmission. Also, this chip will get the same to a slight improvement in gas mileage.



IF YOU HAVE A 1986 or 87 2.8L S10 you would have to change to the newer computer system to use chip.

Chip is good for 12hp and improved power above 3000 rpm.

Also, this is a performance chip. You must run either 91 octane with stock 195 thermostat or you can run 87 octane with a colder than stock thermostat like a 160-180 degree stat.

This is a replacement chip for the factory prom inside your computer. Not a resistor that alters the sensor reading to fool the computer into doing something its not suppose to do.

Chip is installed in factory holder and is just pull the old prom out and replace with this one. You can put the stock chip back in just as easily. This is much easier than trying to reuse the factory plastic holder from the stock chip.


So , if anyone has heard of these chips or knows anything about it let me know.If I could get an extra 12 HP or even half of that for 80 bucks , that doesn't soundlike too bad of a deal <img src="/forums/images/graemlins/smile.gif" alt="" /> But if it only works on stock 2.8 and not modified 3.4 , then its not worth getting.
