your build.
A tune is written for the exact parts on your machine. These are the twelve things we ask about every build. Fill them in and your email to the tuning team writes itself.

Your email app opens with everything filled in. Running a Power Vision 3? Attach PV_INFO.TXT before you send; here’s how to get it off the PV3. Your answers stay on this device until you clear them.
Why we ask
Every part changes the tune.
How much air moves
Everything the air passes through changes how much of it gets in and out, and the fuel has to match. A free-flowing exhaust or a bigger plenum is a different engine to the ECU.
When the valves open
Cams change where the engine makes power and how high it wants to rev. On the Can-Am big turbo, stock cams target 8,500 rpm and Packard cams 9,200.
What the ECU can see and feed
A MAP sensor has a ceiling on the pressure it can read; past it, the ECU is guessing. Injector size sets how much fuel each pulse delivers, so the tune has to know it to the cc.
Where the tune lives, what it burns
A stock ECU, an Emtron and other standalones take completely different files. And every tune is written for one fuel: running a pump-gas tune on race gas leaves power on the table; the other way around is how engines get hurt.
Questions
Questions riders ask.
Where does this go?
To [email protected], the tuning team’s inbox. Include your order number if you have one.
I’m running a Power Vision 3. What else do you need?
Attach the PV_INFO.TXT file from your PV3. The Power Vision 3 guide shows how to copy it off the unit.
I don’t know what injectors or MAP sensor I have.
Put “stock” if you haven’t changed them, or tell us what you know in the notes. If you bought them from us, your order number covers it.
I bought a Z10 or Pro R tune. Do I fill this out?
No. Your tuner portal already asks for your build. Open it from your order email or at packardperformance.com/tune.
