Ethanol content should be limited to 30-40% when blending E85 with gasoline. (35% recommended) Please contact us if you are interested in the 91 octane version.
An aftermarket clutch is REQUIRED, as the stock clutch will not survive this torque level. An upgraded intercooler is HIGHLY recommended. This tune is designed only for use with the factory turbocharger and is not suitable for used with upgraded turbochargers.
Suitable for use with the factory intake or a QUALITY aftermarket intake that keep fuel trims in check such as the
PRL High Volume Intake.
Aftermarket downpipes are also fine.
