With MHD Stage 1 , the car has more torque than in previous version . 0.25 stage 1plus. The great thing, in WOT the car doesn't "fall on its nose" anymore. The power is now linear between gears. Its true Boost between shifts seems to work much better now. Update: After driving aprox. 100miles , the car seems to have adapted and the crunking during downshift is gone.
