If purchasing one of our core PCM's we ensure that the PCM is fully operational but we don't guarantee the cosmetic appearance. PCM's returned for a core refund will be tested to verify it is a good reusable core before a refund is issued. Please note the following on our Core Charge Program. It generally takes 3-4 business days to custom program a PCM and ship it. Speedometer and transmission re-calibrated for aftermarket tire size and gear ratios. Torque converter tables optimized for aftermarket stall converters. Extended shift points to match the extended rpm range for vehicles with aftermarket camshafts for example. We are getting rid of those “lazy” slow shift times that can be found in stock form. Transmission calibration is completely optimized throughout. Improved throttle response from reworking a collection of different parameters within the calibration. Torque management can be overly aggressive in stock form hindering performance. Idle airflow, fueling, timing to name a few among other parameters will be gone through more extensively on vehicles with aftermarket internal engine mods such as camshafts for nailing down that good drivability. Most aggressive timing maps will be able to be calibrated when the customer uses premium fuel. Timing tables carefully and efficiently calibrated for maximum performance for 87, 89 or 91-93 octane fuels. Stoichiometric ratio set for the ethanol blended fuels that are found at the gas pumps these days. Air Fuel ratios optimized for wide open throttle operation MAF (Mass Air Flow) and Volumetric Efficiency tables optimized. Performance calibrations maximize performance and mileage while retaining that stock drivability. This is the details that go into each and every calibration: Mail order tuning is available for customers in the continental US only.Please Note: The core PCM option is not available for the following vehicles: 97-98 Corvette, 1998 Camaro, 1998 Firebird, 2005 Corvette, 2005-2006 GTO, 2005-06 Envoy & Trailblazer.They are used cores that we test to be fully operational.
