This is a build that has been over 4 years. I've done everything myself and I've been doing it while full-time student and working full-time. I wanted this envoy to rival the Trailblazer SS (same family) and to put a serious smackdown on the track.  THIS WILL BE (to my knowledge and checking with Trailvoy.com/forum) THE ONLY ENVOY THAT IS TURBO CHARGED

The hp at the wheels is around 425. It can be tuned down to 369 or up to 475+.

Best 1/4 Mile was a 14.64 @ 109mph

Go Fast Goodies
- Stage3 ECU/PCM tuned. (faster/stiffer shifting, better timing and acceleration, more tq/hp through air/fuel ratios, shift timing, rev limiter, throttle body.)
- AEM wideband air fuel sensor/controller/data logger - Borla / GReddy exhaust piping
- Flowmaster muffler/cat Highflow 3" catback. (all bends and welds done by me  NOT A BOLT ON...completely custom)
- AEM Cold Air Intake / air sensor
- Upgraded pistons, injectors, plugs, wiring, ignition (various companies)
- Upgraded Fuel Rail,AEM fuel Pump,AEM fuel Pressure Regulator (various companies)

*upstream wideband air/fuel
*downstream narrowband airfuel
*trans temp (from GREDDY transmission cooler I put in)
*vacuum pressure
*oil temp

*** My goal is to finish fabricating the intake manifold and supporting parts for the Garret turbo I plan on installing over the winter to surpass the SS and a lot of competition on the drag strip. This would bring the HP numbers to an estimated 750+ at 22Lbs of boost. this should be done by summer of next year.***
