General Information on TBI in Later 80's Trucks

[burger]

Thanks for answering the questions that I've asked so far. I'm new to these trucks, so what's old hat to you is new to me.

My next question is a general one about the TBI found on later 80's trucks.

Is it any good? What type on injection is it? Is it an "electronic" QJet or is it more modern like the units found on early-90's trucks? Do they provide better mileage and driveability? Does anyone have pictures?


Thanks,
Ed
