Hey guys, I recently installed the Cobb SF intake w/ box in my '12 WRX. I tuned with the AP using a Stage1 + SF 91 octane map. I use 92 because it is the only widely available high octane gas in Washington State. The map stated peak boost should be at 16.5 (+/-1psi). I drove it easy for 100 miles then recorded a few 3rd gear pulls. I noticed a consistence over-boost to 17.5psi (within the +1 psi stated by Cobb). I went out driving a few nights ago and noticed a max peak at 17.8 then later a 18.0!
I decided to try the LWG map and see if it would put me closer to nominal, but i'm still showing logs of 17.5psi
Should I try the super LWG map? Could this increased boost be a result of using 92 octane with the 91 map? (the map does say for 91 and 92 gas though).
