Power by Trifecta

Trifecta Performance specializes in delivering custom powertrain control module (PCM) programming to the high performance community. Trifecta Performance offers both local “dyno” tuning services in the Seattle, WA area , as well as mail-order custom PCM programming services.
Trifecta Performance has also developed a product, called the GT Tuner (see below), which allows car enthusiasts to perform their own PCM programming, quickly, safely and easily.

UPDATE (06/25/09) Trifecta's HHR SS/TC

Wanting to push the envelope as far as possible, Trifecta has purchased a 2008 Chevrolet HHR SS/TC. There's some new LNF tuning in the works but so far we've pushed this little engine to over 30psi on the stock turbo using Trifecta's own "Infiniboost" OS tweak!

Look for major enhancements and new tune features over the next few months with our LNF tune!
UPDATE (04/19/09) Trifecta Tunes two Ariel Atom 2 cars!

Two local owners of LSJ-equipped Ariel Atom 2 cars hired us to dyno tune their hot rods. The first car has a Harrop TVS blower on it, LS4 throttle body, and water/methanol injection, and the second car has a smaller pulley on it! Pictures to follow!

Custom tuning for stock Ariel Atom 2 PCM

Many Ariel Atom 2 owners end up purchasing another PCM from a regular Cobalt 2.0 SS/SC just so they can do their own custom programming. No more is this a necessity, we are now able to offer full custom programming via our handheld or programming cable on the native Atom 2 PCM!

Support for 2010 Camaro V8

We are now able to offer custom programming for the new 2010 Camaro V8 (including TCM programming)!

Custom ECM / "doorstopped" ECM unlocking

Have a locked E37, E38, or E67 ECM? Have an ECM with a bad flash that no longer communicates with you? No problem, we can now unlock/restore those units so you can resell them.

UPDATE (01/17/09) 2.0 TC (LNF) Custom Tuning & More

Thanks to a local customer with a 2008 Cobalt SS/TC, we can now offer custom tuning for the 2.0 turbocharged engine (LNF). We've been told that we hold the record for the most amount of power out of just a tune on these cars (we hit 301WHP/334WTQ on a stock 2008 Cobalt SS/TC - that's a gain of 52HP and 74TQ). The LNF engine is an amazing engineering accomplishment and we're proud to offer an equally amazing tune for it!

As with every tune that Trifecta offers, no ECM swap is needed, and no relearn procedures are required (such as dreaded clutch-position learn).

Data logging support for J1850 vehicles in GT Tuner!

We can now "remote tune" any J1850 OBD2 vehicle (LS1, Gen III truck) with our GT Tuner. Get hands-on dyno tuning quality from a mail order tune!

Now offering 'Independent Tuner' dealer opportunities!

Under our dealers section you will find we now have Independent Tuners listed. Independent tuners are those who purchased the EZ Flash cable and are authorized to resell our tunes in their local area! To learn more about becoming an Independent Tuner just send us email!
UPDATE (08/24/08) HHR custom programming (2.2 and 2.4) available now!

CJ's Mods and More helped us dial in the HHR tune using our built-in data logger! We're pleased to be able to offer HHR tuning for both the 2.2 and 2.4, equipped with either manual or automatic transmission!

Data logging support for CAN vehicles in GT Tuner!

Due to the popularity of our custom tuning for the 2.2 Cobalt with turbo builds, we decided to add data logging support to our GT Tuner. For customers with CAN based vehicles (LS2+, 2007+ Trucks, 2.2L Cobalt/HHR, etc.) we can now tune as accurately from 3000 miles away as if the vehicle were right in front of us on the dyno! We are working on support for the data logger on the J1850 VPW vehicles (OBD2 LT1, LS1, "black box" Vortec, etc.) and expect to release support for it within the next 2 months.

EZ Flash "do it yourself" programming cable for sale!

Several customers have asked us about having the ability to change the tune on their car when they like (e.g. go back to stock when going to the dealer for service). In response to our customers, we now offer a programming cable for purchase, called the EZ Flash cable, for $250. This cable works on any Windows XP or Windows Vista computer with a USB port (and includes the required software). Additionally, there is a discount available on tunes when purchased with the cable!
UPDATE (07/04/08) Happy 4th of July! Have a fun, and safe 4th of July.

We're the only outfit around offering custom tuning for these engines. This tuning is being offered through Clear Image Automotive.

UPDATE (02/25/08) Wow! We've been busy! We just added support in the GT Tuner for many "CAN" bus vehicles, including the LS2, LS3, and other Gen IV engines. We can now offer programming for these vehicles' engine controller (transmission controller programming will be available very soon). Custom programming for these newest generation "CAN" bus vehicles will be $299.99, but we will offer an introductory price of $250 for a limited time.
UPDATE (01/21/08) Lots of updates! We've added several cars to the customer dynos page, and a link to extensive dyno testing we did on a 2006 Pontiac Solstice, in conjunction with Clear Image Automotive, and Meridian Performance Services. Click here to see the full report! We don't support the Solstice in our GT Tuner quite yet, but will *very* soon!
