The tuned pcm I got for my chopacabra cam that I installed on my 05 chevy 1500HD 6.0 lq4 is great. Build is mild hc LM7 with BTR stage 2 truck cam.
Got the ecm fast and the tune by Zak is great. Local start ups getting 400$ to buy license and guess work. Very happy with service and would recommend. Installed PCM and engine fired right up with idle around 750.
Mailed PCM to them, and they tuned within 3 days and on the way back. Outstanding job.įilled out spec sheet on my 5.3 ls build for 2006 Silverado with Truck Norris cam swap.

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:
Once you add performance modifications to your vehicle you should have your PCM tuned.
