Yesterday I had another NASIOC guy come over so we could flash an XPT Stage 1 map on his stock car. Should have been np, flash it, few logs, good to go.

Not so much.
I looked at the XPT stage 1 and stage 2 maps and compared them. Stage one has higher boost, and for longer than the stage 2. Stage 1 has way more timing advance, and has more aggressive fueling. To me, it looked like the maps had been switched or something. So, being one to follow rules, I flashed the Stage 1 map on the car, went for a spin, and started logging. 2nd gear it seemed happy but it started pulling timing about halfway through, although IAM's stayed at 16. Sometime between the 2nd and 3rd gear pull though, it dropped IAM down to 12 at 3200prm/1.8. took it back to the house, and looked at the map, figured I could smooth some of the fuel map, which has some wild swings in AF at totally random spots, on at the spot we dropped IAM. Reflash, back out, and it dropped to 8, same exact place. Now confusion set it, flashed stock map back on and figured id work on it later.

Needless to say, I am currently not to confident in any map I find there, be it XPT or personal custom tune. I am going to buy a staged map from XPT just to compare the differences between the paid for and free map. Im sure it will be extensive, considering how little work went into the free stage 2 map.

MotS? Maps are alot like free drinks from strangers in a bar. It's probably alcohol, but you have no idea how good it works.
