Im installing a RD sports(U.S.) ECU tune this monday. I talked to the Rep Federico he seemed like a very nice gentleman with lots of knowledge of the industry and tuning. Before i bought my X6 5.0 i was really looking into the E92 m3 and i followed his development of the stroker m3 and the end result looked awesome. So i called in asking if he had anything for our cars and he gave me the rundown about his new ECU tune supposedly it adds +93 HP and +84 Torque
. Just wanted to know if anyone has had any experience with RD sports/Federico with there x6 or any other car. Thanks
