Hi!

My first post here as per forum rules.
I want to learn more on efi tuning. My interest is more on the fuel economy side.

Current premium gas price here where I live is around $8.5 a gallon, RE85 is around $4.5 a gallon.

My ride is '93 astro LT AWD.

Lets Tune!!

Ive been reading a lot about this pcm stuff but I still seem to be a bit lost. What I mainly want to do is to monitor whats happening with my trucks motor. Basicly monitor fuel economy and errors and fix them. Maybe later I might buy equipment to burn new bins. Ive downloaded Tunerpro rt software but Im not sure what def file is the right one? My truck is 1993 astro with 16168625 pcm AWD, 3.42 ratio, 4.3l Z LB4 engine, ABS, 4l60e trans, export model.
