'88 5.7 Super Chip superchip?

[NMNorsse]

My truck is a '88 5.7 K1500.

Today at the treasure yard I stumbled across an '88 C2500 5.7 and the ECU had a "Superchip" sticker on it. The chip in the ECU had a superchip sticker on it too. In the glove box the previous owner had saved the magazine ad for the ADS Super Chip stapled to the installation instructions. Original price was $51.95 in 1988!

The part number on the superchip is 78FJ5525YF

I can't find any specs or data for it online.

Is there any harm in trying it in my truck?

My ECU label says :
Serv. No. 1227747
860061 E180700340
16120061

I wouldn't until I at least looked at the .bin and compared it to mine.

How do I do that?

I emailed Holley and here is their response:

Thank you for contacting SuperChips!

We do apologize, but there is no way for us to tell what is on the chip as any related equipment has been out of production for over 20 years.

If the product is not working as intended, we would suggest removing it.

I put the chip in and it is running fine. I don't really notice any difference but have only driven 20 miles or so on short trips. I'll check the fuel consumption when I refill the tank to see if I notice anything there.

It's probably ok. I don't recall seeing different part numbers in the ads for 1500 vs 2500's. Different motors ya, but if they are both 5.7s and the same year your probably safe.
I find it ridiculous that they couldn't match up part numbers to say if it would work. Silly.

I've got the original ad and it is the same chip for 1500/2500/3500. The motor and tranny was the difference between the chips. I'll see if I can post a pic of the ad for posterity.

Not really. Holley bought the trademark but probably not the intellectual rights. They could produce products using the trademark but had to put their goodies under the label.

Fair enough.
