something strange
whats up guys,,
i have two cousins that got M2. both are modified such as DP cat less and catted, full cat less exhaust, methanol and JB ,etc.... the thing is one of them took the car to the track and he dropped the rear tires pressure from 38 to 20 psi. he change the settings to sport plus to unleash the beast, but for some reason after driving it on the track the car goes back to comfort mode? strange!!! so what we did we filled up the tires again with air to make it as normal. the car is fine and doesn't flip between mods? the other case, my cousin got the same car but with direct methanol injection kit and JB4, he was trying the car performance for the half mile run. done the same tires pressure. same thing happened car flips from sport plus to comfort!!! filled up the rear tires again to the normal pressure and the car runs great! strange isn't it? HELP!

The TPMS threads in the Track section provide a lot of details several of us have learned at the track. Give them a read thru. |
