With the ridiculously good deal on X51 available at Suncoast right now, I ordered the kit. $5795 seemed too good to pass up. Has anyone else added X51 to their .2? What did your dealer charge you for labor? Any techs here do an install or two? How long did it take? Looks like swapping the turbos, changing the fan/engine cover and flashing the ECU in PIWIS. Anything else to it? My car is a 2018 C4S Coupe with Sport Package (SC, PSE, RWS). Those that did add it, was it a substantial difference in performance post-install? Thanks in advance!
