VAST is proud to present the latest in-house Continental SIMOS SID21.1 DCKA (and others) Engine Tuning. Gains of 80-90hp and 120ft-lbs of torque on 91 octane are very repeatable and can be even better on 93 octane. We recommend to 91 octane or above for our tuning.

 Custom tuning options are available for various levels of hardware. With the 991.2 3.0 Turbo, we do recommend testing diverter valves, new factory spark plugs between 25-30k miles set with our specified gap and torque procedure. We also recommend a high flow air filter, such as BMC. 

 We can put together customized engine and tuning packages for you to best suit your needs. 

 Engine computers may be mailed in for tuning or can be tuned on-site. Added costs are involved with remote tuning.
