Things to know before Dyno Tuning
- Timing set at 10-degrees BTC (SPOUT out) for Ford EFI vehicles
- TDC verified, particularly if balancer has been removed/replaced
- Fuel pressure set to 39.5 psi (vacuum off) for EFI vehicles
- For blown cars, New copper spark plugs properly gapped .025 - .035 and installed
- Make sure that FRP(Fuel Pressure Regulator) or FRP sensor is connected to the boost side of the blower on blown applications
- Make sure all spark plug wires are good, including coil wire
- Make sure PCM and its diagnostic ports (including OBDII) are functioning properly
- Make sure all the tires are in good condition
- Make sure all belts, hoses and the cooling system are in good condition and up to the task
- Oil, coolant and other leaks should be fixed prior to arriving; badly smoking cars should be repaired before arriving
- For blown cars, be prepared to disconnect the FMU(Fuel Management Units) have vacuum line plug/cap available
- For blown cars, if no FMU is used the injectors and fuel system, pump, lines ect. must be sized properly for the power level expected: Major engine damage could result.
- For blown cars, the ACT must be placed after the blower (not before like on '94 & up vehicles)
- For blown cars with returnless fuel systems, it is must to use a 2003 Mustang Cobra fuel tank and pumps. Normal EFI pumps will not work on a returnless system
- Cars with returnless systems cannot be properly tuned if using a 'wet' nitrous system
- Exhaust leaks will dramatically affect the air/fuel measurements taken. If possible, repair any/all leaks prior to your appointment. We may not be able to provide meaningful air/fuel results for vehicles with significant leaks.
- Make sure that an O2 exhaust bung is welded in your exhaust at/near the header collector on drivers side of the vehicle. This is the only way we do our tuning. We can provide you with a bung & cap FREE of charge with any tuning package.
