Trifecta's EFI and Dyno Tuning Services
|
|
|
|
Looking for maximum power and the dyno sheet to prove it?
Trifecta Performance specializes in dyno-tuning GM EFI vehicles.
We have experience tuning GM TBI (Throttle Body Injection), GM TPI
(Tuned Port Injection), LT1/LT4 engines, Vortec Truck engines, Gen
III V8s (LS1, etc), and Gen IV V8s (LS2, etc).

Our approach is a bit different from other engine tuners. Many
tuners will charge huge up-front costs because they are estimating
they will need to do follow-up tuning work. We only charge for our
time. Also, we do not have an expensive shop we expect customers
to pay for. No matter where you are, we will find the dyno-shop
that is closest to you (and meets our requirements) and set
everything up. All you have to do is show up with your vehicle.
|
|
|
|
|
Last, but certainly not least, we have the ability to mail you
programming updates. Let's say you decide after our appointment
that you want your automatic transmission to shift a little more
firmly. We can ship you our exclusive GT Tuner with your update
and you can update your vehicle yourself.
|
|
|
|
|
We also provide general diagnostic services at the rate of
$100 per hour, depending on the situation. Give us a call.

We are proud to provide local services to western Washington
state including Seattle, Tacoma, Olympia, Bellingham, Everett,
Greater Eastside (Kirkland, Redmond, Bellevue, Renton), Kent,
Auburn, Puyallup. In WA state, but not in these areas? Give us
a call, we will do our best to accomodate.

The fine print: Prices above do not include dyno
time, which can vary dramatically in price. Prices
include up to two hours of tuning time, in excess
of two hours, the rate is $100/hr. Some vehicles
may require purchase of a 'tuning license', which
costs $100. Some vehicles may require hardware to
be purchased (e.g. TPI) which is not reflected in
the pricing. Updates sent out via GT Tuner are $50
+ shipping. Updates performed in person cost
$100/hr. Outside the Seattle, WA area,
transportation expenses may be billed. For a
detailed quote, please
email us.
