Dyno Prep Checklist
The smoother your prep, the more pulls we can fit in. Here's what to bring (and what to check) based on your build type.
Universal — Every Car
- Fresh engine oil
Within the last 500 miles, correct weight
- Coolant topped off
No leaks — the car will run hot on the dyno
- Good tires
Enough tread to grip the dyno rollers safely
- Battery secured & charged
Weak batteries cause voltage drops mid-pull
- Wheel nuts torqued
Check all four corners before you arrive
- Remove loose interior items
Tools, jack, spare tire — leave them at home
- No fluid leaks
Oil, coolant, fuel, or trans leaks will halt the session
- Base map / previous tune file
On USB or emailed ahead if we didn't create it
Turbo / Forced Induction
Boosted builds need tighter prep. Leaks, heat, and fueling margins kill dyno time fast.
- Turbocharger & manifold
Installed and all bolts torqued to spec
- Wastegate & springs
Bring extra spring rates if you have them
- Boost controller
Electronic or manual — confirm it's plumbed correctly
- Intercooler & charge pipes
All couplers tight, clamps double-checked
- Blow-off / bypass valve
Recirc or vent-to-atmosphere as mapped
- Downpipe & exhaust
Must flow freely — no crushed or restricted sections
- Oil feed & drain lines
Restricted feed if required by turbo manufacturer
- Coolant lines
For water-cooled turbos — no kinks, good clamps
- Vacuum / boost reference lines
All lines routed away from heat
- Spark plugs (1-2 steps colder)
Gapped to tuner spec — bring extras
- Injectors sized for goal
With flow sheet or part number confirmed
- Fuel pump(s) & wiring
Full voltage, enough flow for target horsepower
- Wideband O2 sensor
Installed in downpipe before the catalytic converter
- EGT probe
Recommended for boost levels over 15 psi
All Motor (Built NA)
High-compression, big cam, ported head — every detail matters when you're chasing NA power.
- High-compression pistons & rods
Installed — bring compression ratio if known
- Camshafts
Spec card (duration, lift, LSA) if available
- Valve springs & retainers
Matched to cam lift and RPM limit
- Ported cylinder head
Flow bench numbers help, but not required
- Intake manifold
Gasket sealed, all vacuum ports capped or plumbed
- Throttle body
No binding, TPS calibrated before arrival
- Headers & full exhaust
Primary tube length and diameter if custom
- Spark plugs (colder heat range)
Gapped correctly for high-compression / RPM
- Injectors (if upgraded)
Flow rate confirmed for rev limit and cam overlap
- Wideband O2 sensor
Critical for dialing in VE and fuel targets
- Engine management
Standalone or reflash cable/software ready
- Dyno cooling fan recommendation
Ask if your shop provides adequate airflow
NA / Stock to Mild Bolt-Ons
Less hardware, but the basics still matter. Fresh plugs, clean filters, and the right fuel.
- Fresh spark plugs
OEM or one step colder, properly gapped
- Clean air filter
Or upgraded intake if installed
- Headers / exhaust (if modified)
Cat-back or full system — know the brand/model
- Basic bolt-ons
Intake, throttle body spacer, etc.
- ECU / reflash
Stock or tuned — bring cable if reflashing
- Wideband O2 (if tuning standalone)
Not needed for OEM ECU reflash-only sessions
- Fuel type you plan to tune on
Pump 91/93, or bring race gas cans if applicable
