Came across this thing called TMC Tuning Box... A new friend threw it at me and I gave it a try... It is said to have 9 maps?? Apparently the map 9 supports an aftermarket downpipe.... Wasn't expecting much but did a test run... Launch at around 2K rpm again and got 5-sec flat.... best time I've gotten so far.... about 0.2 sec faster than my JB stage 1. I'm excited about upgrading to JB stage 2 but for now the TMC is staying under my hood.... at least until after I have another run with the Challenge HFC DP!
