I'm New to the Grand Nationals. I have a stock 1987 GN> i plan to bracket race it with limited street use. What else besides a MAF Translator and Power Logger what would I need to tune this car. I plan on 50# injectors and chip, Alky injection, 3" flow masters, Hi stall conv. larger turbo. etc. Where do I get or find this info? how do you actually adjust anything like air/fuel settings and thing like that? any help would be greatly appreciated. Thanks Tom

Start reading at the link below. You should plan on a larger intercooler and I would go with 60 lb injectors. Less chance that you'll need to trade up later.

Vortex Buicks

Agreed. Do the 60# injectors. Great injectors with plenty of head room.
The Translator will allow you to run the more reliable Chevy MAF's.

If you want good flowing exhaust system on a turbo application (is this your first turbo car?)

Rule #1 Reduce post turbo backpressure to as low as possible!!!!!!!!!
This means running flowbastards is one of worst applications for a turbo car. Any high quality straight through muffler will work so much better (no not glasspacks either).

If you can afford it, only buy your exhaust system once by going with a large (2.5"-3") stainless. Like this:

Fuel is adjustable with combo of adjustable fuel pressure regulator & adjustable turbotweak chip. Timing can be changed with chip too.
