Sinister Performance, LLC.

Custom Chip / ECM / PCM Reprogramming & Tuning

For most GM Cars and Trucks (EFI only)

We are dedicated to tuning your vehicle's engine computer to attain maximum performance and the best drivability possible while keeping the powertrain reliable.  We don't only focus on Wide-Open-Throttle performance, we also focus on all aspects of vehicle operation aimed at making your total driving experience more rewarding.  While we specialize in vehicles that have engine swaps done to them, we also have a lot to offer those vehicles with bone stock engines or those with highly custom builds.  Mild to wild, practical to radical, we will do our best to get your vehicle running as it should.

NOTE: The mem-cal adapter is a device that plugs in between the computer and the factory mem-cal on most 1986-95 applications. This adapter accepts individual EPROM chips we can ship you which can be installed by the end user without requiring you to ship us a mem-cal to be reprogrammed. Use of this device can save money and downtime when extensive tuning is required. This adapter must be purchased thru a 3rd party and may not work in all applications. The Purchase of one blank EPROM chip will be REQUIRED with the mem-cal adapter purchase. Blank EPROM chips cost $7.00 ea, but this amount will be refunded to you when you return undamaged, unused EPROM chips (if ordering more than one during the tuning process). Other restrictions may apply to your specific application, ask for details.

In addition, a PCM exchange program option might be available for some LT1-flash and OBD-2 platforms; email for info. (This exchange program is helpful if you can't afford any vehicle down-time. A core charge or other costs may apply. Limited availability.)
