Bog at 5k in 3rd gear
Drove in the the city yesterday and notice 6 knocks when I was going up a steep bridge. After that I didn't notice anymore. Would going up a steep hill cause more knock since its putting more strain to the motor? On level roads the most I've seen was 2 knocks during 50-75% throttle.

Yesterday I noticed going up a (who knows this a guess) 30% or so uphill grade for a split second in fourth gear at around 3500 rpm at maybe 50% throttle I saw a 5 count that quickly ping'd into a 4 count before I shifted to 5th gear.
That was the very first time I saw a 5 count and it was on an uphill climb
I think this is a good ???.........(poor COBB they must be like...."before you had the AP your car probably hit 10's and 15's on knock...and now you're crying about a 5"
)....J.K.
I'm also having the same issue with fuel cut, I ran stg2 cali with a catless tbe for 2 months and not a single issue. Not even knock, now I've hadded cobb intake, ams i/c, walbro fp, meagan o2, i/c piping, now I get a bunch of knock up to 6 counts @ wot. I was expecting this by the way and I will be getting pro tuned and adding cams. This issue does seemed to be caused by the o2 housing in my opinion.

Christian @ Cobb is working on some test maps for me to see if this goes away, he said he will even work on it during the holidays. Christian is awesome

I agree. The added airflow from the 02 housing is fudging up the WGDC table, i think.

well I finally got the over boosting cell last night but the thing is for me I'm not getting any knock at all maybe a 1 to 2 count at most. I dont have anything but a TBE and a cobb cone air filter unless whoever had the car before installed an after market o2 housing it didnt look it from what I could tell though

Thanks for sharing bro...let me know how you like those cams
UPDATE!!!!!!! Christian from COBB sent me a test map to see if it eliminates the fuel cut issue. I installed it yesterday morning right before i went to work. Once I had space I opened up and rpm climbed perfectly to 7k and NO MORE FUEL CUT and zero knock!!!! I continued to test it out all last night and nothing, no hesitation, no nothing.
Christian, your the best!!!!!!!
If anyone is running the stage 2 93 octane and having fuel cut issue like I was please contact Christian. He will hook you up with a test map and it should resolve the issue.
