I have a 2014 sho nonpp with livernois tune downpipe exhaust and 3bar and was running 12.7 mostly on all my runs! Then I decided to add the meth kit from livernois and have took it to the track three different times and the best I could do is 125! Don't know if I'm doing something wrong do I have to hit the test button once before I run it? It dyno at 395 and 444 tq. I appreciate any help with this meth thank you
