This Intermediate ECU Upgrade rewrites ignition timing, throttle mapping, fueling and boost control on the 4.0L M177 twin-turbo V8, so the extra power arrives across the whole rev range without giving up everyday drivability. RennTech rates the car at 574 hp and 612 lb-ft with this upgrade. That is a gain of 48 hp and 80 lb-ft.\u003c\/p\u003e\u003ch3\u003eKey details\u003c\/h3\u003e\n\u003cp\u003eThis intermediate stage for the C 63 and C 63 S makes up to 574 hp and 612 lb-ft, a gain of 48 hp and 80 lb-ft. It is CARB certified in all 50 states, and the OBD2 hand-held tuner flips between tuned and stock without ECU removal.\u003c\/p\u003e\u003ch3\u003eWatch it explained\u003c\/h3\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:8px 0 16px\"\u003e\u003ciframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/dGTikm51Bd4\" title=\"RennTech product video\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allow=\"accelerometer; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen loading=\"lazy\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRevised ignition timing, throttle mapping, air-fuel ratios and boost control\u003c\/li\u003e\n\u003cli\u003eGains across the entire rev range, not just at peak\u003c\/li\u003e\n\u003cli\u003eDeveloped on RennTech's own dyno and road tested\u003c\/li\u003e\n\u003cli\u003eKeeps factory-like drivability and reliability for daily use\u003c\/li\u003e\n\u003cli\u003e93 octane or better recommended for the full calibration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat is included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRennTech calibration for your car\u003c\/li\u003e\n\u003cli\u003eDelivery as listed by RennTech for this model (HHT tuner or ECU flash)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003ctable style=\"border-collapse:collapse\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:4px 12px 4px 0\"\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e54.205C.C63BI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:4px 12px 4px 0\"\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4.0L M177 twin-turbo V8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:4px 12px 4px 0\"\u003e\u003cstrong\u003eRated output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e574 hp \/ 612 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:4px 12px 4px 0\"\u003e\u003cstrong\u003eGain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e+48 hp \/ +80 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:4px 12px 4px 0\"\u003e\u003cstrong\u003eShipping weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eFitment notes\u003c\/h3\u003e\u003cp\u003eFitment is as listed by RennTech for this part number.
