Custom Chip.

I'm getting ready to send off a request to Jet Performance Chips to have a chip burned. However i just have some question that i need help answering.:
What is the the stock gear ration and towing weight of a 1991 Blazer?

Probably 3.42.


Towing weight, not sure.

I don't know as I'd go with Jet.

Check over on thirdgen.org, I believe there have been some very bad issues with jet chips.

Don't know about the towing weight but I have a 6000 lb package so probably around 6..

Just grabbed manual... says 35 lbs of gross weight per 1 hp. Multiply your engines hp by 35 and subtract the weight of the vehicle passengers and luggage.-straight from the manual. don't see a rear end ratio.

why does the manual say that the 88 350's had 160 hp and 235 ft lbs when most people tell me its 210 with 300 ftlbs. I always saw 210 with 300 ftlbs on all the websites. No way a 4.3L v6 makes 20 less hp and 5 less torque than a 350 on the same year. wtf?

at the wheels???? still doesn't explain the v6 to v8 numbers.
