Here are some questions about my car, on the day of remap. I tested out 0-100 on S mode, where i got about 7.3s. After few days later, eventually I Put one of the piggyback which is tapped through the OBD connector and tested out again eventually i got about 8.8s, which got pretty worse. Then i took out the piggyback and tested out again seems like i got about 8.5s or so.Here's the thing, the remapper told me that the remap settings won't run away, so he wouldn't help me check out the remap. I kept telling him about the speed from 0-100 dropped badly and the speed i'm getting from my car seems to be lacking. Question is, will that piggyback eventually override the map settings that are already on the ECU?And is it normal to get about 8.8s 0-100 that way, I already remapped and it seems to be bad.Thanks, please checkout my dyno.</blockquote>
