We will definitely make some changes to our STG1-3 maps for the CA 91 Octane. We are just absolutely swamped getting ready for SEMA.
Will most likely pull out 1-2 degrees of ignition advance at the onset of boost and pull about 1 degree out between 4750-6000K RPM. We run the maps pretty rich overall at about 10.6-10.7-1 but we might add about 10% more fuel.
If you have a UTEC and are using CA 91 you should follow these tips. We are waiting to get some reformulated "winter" gas to continue testing on in November.
