What is the best stock bin to start with for tuning my car? And the right .xdf and .ads files so I can get started Any help would be great. I dont know whether to go with the $6e or the 32b

Thanks
Greg

 

You can either use your stock bin that is with your car or upgrade to the $6E (which is better defined). I note that your car is a 305 5-speed, so the ARAP bin (which many guys with MAF like) will not be the best $6E to work with as it is intended for an automatic.

For $6E 1989, 305 5-speed with 3.08s, the APYS & APYX were for Federal and APYW for California.
