Hello everyone, have a question? In the summer my car time was 100-200 9.8-10s, I have a 200cell sportcat, a chardgipipe forge and intercooler forge. I decided to measure again because it was getting colder weather and now it 10.7-10.8 stably, once it showed 10.4.it's very strange because in the cold it should go faster ... what could be wrong? I tried all the fuel at different gas stations.Thanks!!!
