I'm trying to decide on what prom to use. I currently have the acxs 1088 prom from a 87 305. I have a 350 with 24lb injectors. What I plan on doing is getting a prom right from my gm dealership as I really don't have time YET to try burning my own proms. I can see that coming down the road though. I've thought about getting a prom for a 87 vette but then maybe just sticking with one from a 87 f body. Anyhow I could use some advice on what to get for right now to get me the best drivability. ken

 

There are difference from vette to F Bod calibrations.
You need to get the equipment and just do it right rather then Mickey Mouse things together.
After all it's just an engine your risking.
Besides you'll want to start with the 89 code, and that means disabling the VATS, and a dealer can't do that for you.

 

Hey Grumpy what do you think, stick with a 5.7 f body chip for an 87. I just don't have time right now to start chip burning. As soon as sd are done with the vortec intake I want to be ready to go.
