Putting A Chip In A TBI Truck

[mwilliams55555]

I have a 94 extended cab with the 350/5.7 TBI with the 4L60e, I was putting a carb engine in a 94 State Police car for a customer, he wanted everything not needed removed, wiring and such, even the computer, I swear I only changed the box, nothing else, didn't open it up, but I did notice more off the line power, maybe a little longer interval in shifts, everything else still works 11 years into it being in my truck now

What GM vehicle was it? If it had a police or law enforcement option it would have performance upgrades. Curious as what model it was.

It was a 94 Caprice, was a state police cruiser, removed all the stands and holder for locking down the shotgun, but had another guy do the wiring harness, but did notice the difference in it
