I just found this site and I'm having a blast reading.
I have some questions for those in the know.
I have an '04 WRX Wagon, with an Sti uppipe as the only engine performance mod.
I live in San Diego. The land of alcoholic fuel.
I recently bought an AccessPort and loaded the 91 oct. stage 1 map.
I did not hear any pinging.
After a few weeks I switched to the 91 oct.California stage 1 map
Again no audible pinging.
After mounting sti struts and swaybars under it I got excited, started making the tires scream and loaded the 91 oct. California stage 2 map even without any other exhaust mods.
So far it feels better. And still no audible noises.
Is there any downside to running this map?
Thanks in advance.
I'm a mechanic by trade and welcome any input.
