Default Cobb Stage 1 93+Sf NEW LOGS ! ! ! First Time

hey guys, i just recently flashed a 93+sf map onto my 2012 wrx and just wondering if my car was running safely and optimally. My buddies actually told me that they run 91maps but still continue to put 93 oct gas so there car runs safer (not all gas is created equal is what they told me. if one gas stations 93 oct is not up to standard it can mess with my car thats why they recommended the 91map) , they also cant feel the power loss which i believe is around 5hp according to cobb. So i decided to do a log of my car with the 93 map doing a full throttle pull around 2k-6k rpms. 2nd log is only up to 4k. Let me know what u guys think and if i can stick to the 93 map or switch to a 91 map. Any help would be appreciated. Thanks.

Ps. Using BP 93oct gas with invigorate if some would like to know. Also my boost levels seem low to me but i know there is a +- 1psi buffer so i guess i fall in that zone.


another run but only got up to around 4k rpm b4 letting off. It seems as if i am getting a little tiny bit of engine knock around the 4k area in both logs (i think i read under 2 is safe and somewhat normal?)

Logs look good as far as knock goes. I noticed in your second log boost got a tad high, however this maybe ok. I'm sure someone with more knowldge than me will chime in. Stick with the 93 map.

Your buddies are correct. You can give yourself a little more of a safety buffer running the 91 octane mapping with 93 octane in the tank. The car looks like it is running well on the 93 octane mapping though, so as long as you keep good quality gas in the car it should be fine on the 93 octane mapping.

You are at the lower end of specification as far as boost goes. I would say if the car feels good, leave it as is. If you want to get a little more aggressive with the car, you could try the HWG mapping. Just be sure to keep a close eye on your boost and knock levels to make sure they don't start going too high.
