Hey guys, sorry I'm new to this and not sure exactly where to post this but I did a few pulls last night for the first time and logged them, and I just want to have someone take a look at them and tell me how they look? I have a 2005 wrx with a Cobb Stage 1 map and only running 12psi of boost for some reason :-( I did the pulls in 3rd gear from about 2000-6500rpm and I was WOT the whole time but I'm looking at the log now...I see boost go all kinds of up and down and not consistent at all. Maybe I need to put the stock BOV back on? I have a hybrid 50/50 now... Just got off the phone with Cobb and they said I need to take it to a shop to have them test for pressure/boost leaks from the intake to the turbo?

Any help would be appreciated...just point me in the right direction to get some of these questions asked?

Also, I tried a Dataloglab dyno graph... I am assuming the numbers are to the crank, because there's no way I'm making 230+ to the wheels with Stage 1, right?

Hi,
Seems your wastegate duty cycle gets pegged at about 60%, check your map with Romraider and confirm whether that is close to the set max limit taking into consideration the correction factors.
