great confidence Peter and Kailash. money back guarantee gives double assurance. just out of curiosity : what is after remap there is some mechanical failure? say a turbo failure or clutch failure etc. who will bear the expenses? Remap: what all things are changed on the MJD. i mean which areas are changed/rectified that Magneti Marelli guys havent got it right. i am wondering how one of the best ECU manufacturers havent tuned their ECUs to the best. after remap which all areas are improved in terms of drivability? what rpms will show the differences.
