I have a 1987 Iroc with a TPI 383 stroker. It has a Paxton SN93 supercharger and super fuel management system in it. What is the best way to go about tuning it?

 

Also it's a five speed and has 30lb injectors.

 

There are several ways to go. Using the '89 $6E MAF code is a decent choice. Only down side is when the MAF max's out. Need to use the PE AFR table to continue to add fuel.

If only pushing moderate boost this will likely work OK.

Not sure what a super fuel management system is, it may be OK, or it may be in the way of a good tune.

How do I get that? Is that an ECM chip?

It's bascilly and FMU. It's a Vortec Super fuel managment system. It was installed already when I bought the car. I think it pretty much makes the car have higher fuel pressure and gets more fuel. I think anyway.

 

You have a lot of reading to do. The ECM firmware is in the chip, and is what gets changed to tune. There are several ways to go for tuning.

Yes I know. I know a lot about cars, but I don't know a lot about high performance stuff or tuning. I want to learn as much as possible, so I can do stuff to my car myself.

What would be the best way to go about tuning my car?

As RBob said, you have a lot of reading to do.

 

I guess so. Thanks for the help and the link.
