Sinister Performance, LLC.
Custom Chip/PCM Reprogramming
For GM Cars and Trucks
We are dedicated to tuning your vehicle's computer to attain maximum performance and drivability. We don't only focus on Wide Open Throttle performance, we also focus on all aspects of drivability aimed at making your driving experience more pleasant and rewarding. While we specialize in programming for vehicles featuring engine swaps, we also have a lot to offer for those stock vehicles with just the most basic bolt-ons to complete high performance build-ups. Mild to wild, practical to radical, we will do our best to get it running right.
We currently offer "normal" support for the following platforms:

SHIPPING POLICY: PLEASE READ HERE
USA SHIPPING RATES:
Shipping for individual EPROM chips: Standard shipping is $2.00; Priority 2-3 day, Express 1-2 day, FedEx Next Day and insurance are $EXTRA$
Shipping for EPROM-in-carrier or MEM-CALs: $6.00 USPS Priority Mail 2-3 day; Insurance, Express 1-2 day, and FedEx Next Day Air Guaranteed are $EXTRA$
Shipping for PCMs: $14.00 per unit via USPS Priority 2-3 day insured; Express 1-2 day and FedEx Next Day Air Guaranteed are $EXTRA$
Canada, International, and off-shore shipping costs extra. Ask for details.
Shipping: All orders shipping via USPS First Class Mail and Parcel Post will only ship out once per week; usually on Monday or Friday, depending on when orders are received. I strongly encourage the optional upgrade to USPS Priority Mail (if applicable) if you desire quicker return shipping service. Exceptions may be made for special circumstances. Orders using Priority or Express shipping options will still be sent on the day they are ready to ship. Shipping prices applicable to continental United States addresses ONLY. Canada, International, and off-shore shipping costs extra.
NOTE: The mem-cal adapter is a device that plugs into the computer between it and the factory mem-cal/chip 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. One EPROM chip will be included with the mem-cal adapter purchase. Additional EPROM chips cost $7.00 ea, but this amount will be refunded to you when you return undamaged, unused EPROM chips. 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.)
