Cobb stage 2 91acn boost question
I recently went stage 2 in my 07 sti and was wondering what my target boost should be through all the gears. I'm running a titek catless dp with a greedy ti-c. I'm hitting around 13 psi in 1st about 14.4 In 2nd then 16 in 3rd. Using a larger restricted pill recomended by Cobb. With the stock pill it feels so much faster. I'm hitting 15.6 in 1st then it says 18.4 in 3rd. Am I boost creeping with the stock pill? Also is 18.4 the max psi the ap can read

yeah that's sounds normall i have the same reading when i was stage 2 on my cobb ap. i still have my cobb ap2 but i just recently upgraded my set-up to a gt30r though. even with my new tuned from dyno comp it still reads through each gear the boost increases. so your fine. i also hit 18psi at higher gears on my 06.
