Might be a long shot but I'm trying to find a stock 350 TBI chip. I have a 92 Camaro with 700r4 that had a 305 TBI that I swapped out for a 350. During the process I swapped in an LT1 cam. As you can expect the 305 tune is way off for this combo. I would like a stock 350 chip to make tuning easier and to run better. Does anyone have one?

 

I have a atjp code prom for $65 shipped

 

Would that work with my 92 ecm? I'm still new to figuring out what works with what

 

It’s from a caprice and will work with 89-92 tbi 1228746 350 automatic transmission.

 

I sent you a PM

 

To the OP, I'm trying to find a upgraded chip, I'm gonna change to the cooler thermostat and put something similar to a jet chip. Is there anyone on here that programs chips, if so I will give you my chip, my car is a 350 with an auto.

If you have tpi I have a Hypertech thermomaster for $55 shipped.
It will work on 90-92 tpi speed density 350 automatic transmission.
