If its a maf, itll run if you use stock or close injs.
It wont run well if u have a SD car.

The maf will help, It will need a lot of tuning to run well though. The maf will cause you headaches in the long run though. It will need a lot more fuel that the stock chip will provide, I wouldn't run it hard until it's tuned. I'd suggest a wideband Air fuel ratio gauge as well. My 355, with afr heads and a XFI280 cam would lean out at idle, running an ARAP bin and 36# injectors. Your extra cubes will compound that problem greatly. No aftermarket chip will work with that combo either, you will probably have to learn to tune it yourself. It is hard to find anyone that is familiar with or willing to burn chips anymore.

So are u saying the stock chip will help? Cause I can get one burned.. And why the gaudge? Do you have one? What's the reason and max air? I just want my car to run right.

Yes, a properly done chip is the right way to go.
88 has the coldstart (9th) inj.
