This is a discussion on A Closer Look at the OEM CLA250 Turbo within the CLA Performance forums, part of the Mercedes-Benz CLA Forum category; any update with the tune? give us some good news...
I would assume needing a FMIC is a given. What's CB25?
Black CLA250 - Premium, Multimedia, Sport, Panorama roof, Bi-Xenon, Window Tinting (50%/35% Front/Rear), Pedal Commander, TurboKits Billet BOV spacer,
Bridgestone Blizzak LM-60 RFT (Run Flats) mounted on 18x8 Anzio Turn Bright Silver wheels with TPMS sensors for winter driving.
Daily driver: 2015 Silver Mazda 3s Touring Hatchback, 6-speed manual transmission
Yes, we would not suggest pushing the kind of power our turbo upgrade will make through the stock FMIC. Now we would love everyone to use our FMIC, it;s the best one on the market at the best price, but if you already have one, it should suffice.
