No Farkas they were the same car. STAGE 1 meaning 0 mods stock intake stock exhaust. I had used the map on my car and pulled more out of it to base safe for others cars. This why i tested the map on the cars for an hour or so.
I never charged the person for a tune it was a basemap and verify. It just so happened the basemap was from my car as it was a 03 wrx.
02-5 wrx ej205s are mechanically the same.
It started out as just a downloaded rom at the request of a fellow subaru member. Then over time it became more custom. I just so happened to own a Tactrix cable and understood what was going on. I flashed many many many cars with maps people supplied over time. It just so happened I knew the map I used on the other stage 1 flashes had been tested pretty hardcore on my own ride and dynoed.
This is no diffrent then how COBB Stage 1 and 2 maps work. Actually COBB uses MORE timing and leaner AFRS.
People came to me asked for Stage 1 / 2 flash , I suggested various ones that I had used and made sure things were kosher after reflash and driving.
